3.2 Controlled Closing/Opening The purpose of controlled closing/opening is to minimize the energizing/de-energizing transients (voltage transients as well as inrush currents). Take the phase A controlled closing processing of a capacitive load for example, in order to avoid switching transients, the making instant in this case shall be at voltage zero. After the controlled closing detector operates, the device enters the controlled closing program. It will determine a reference time instant T0, related to the phase angle of the busbar voltage. When this has been done, and after an internally created waiting time Tdelay, the controller will then give an output closing command at time T1 to the circuit breaker. Then, after the delay time of secondary circuit Tcdly and the make time of the circuit breaker Tclose, meanwhile subtracting the pre-arcing time Tpres, it reaches the pre-programmed target point T3 (a voltage zero). All of Tclose, Tcdly and Tpres have been pre-programmed into the controller. The circuit breaker will then make the closing at the correct time instant and minimize the switching transients.

PCS-9830A Phase Controlled Switching Device Date: 2012-09-20
3 Operation Theory
Tcdly is the delay time of secondary circuit, mainly the operation delay of the mid-relay and IGBT; Tpres is the pre-arcing time; N can be 1, 2, 3··· For the controlled opening process, it is similar to the controlled closing process. Moreover, there are real-time compensation function and adaptive function in controlled closing/opening, as shown below.
3.3 Real-time Compensation Function Deviations from the intended targets may be caused by variations in the operating conditions. The operating conditions that may cause changes of the circuit breaker operating times are, for example, gradually increasing contact burn-off caused by many switching operations, change of ambient temperature and variations of the auxiliary voltage. The real-time compensation mode is especially meaningful for circuit breakers that are not operated frequently, or the external parameter change influencing circuit breaker behavior can be considered as major. In the compensation mode, any external parameter variation giving a known dependency can be compensated for by suitable sensors. The sensors are optional and are to be ordered separately. The internally created waiting time Tdelay is, Tdelay=N*20ms-Tclose-Tcdly+Tpres+△Trt Where: △Trt is the real-time compensation time. The following are three examples of real-time compensation, based on ambient temperature, control voltage, and standing time respectively. In addition, there are other variations in the operating conditions to real-time compensate for the controlled closing/opening. 1.
Real-time control based on ambient temperature It is studied that the switching time of the circuit breaker relates to the ambient temperature. Usually, the lower the temperature is, the longer switching time is. Considering the affect of the ambient temperature, the device detects the ambient temperature and calculates the time △Trt according to the temperature compensation curve pre-programmed into the device.
2.
Real-time control based on control voltage After a large number of experiments, it is found that the switching time will gradually reduce as the control voltage gradually increases, but when the control voltage is in the rated voltage of the range 85% ~ 110%, the time deviation is small. According to the control voltage compensation curve, the device calculates the time △Trt to compensate for Tdelay when needed.
3.
Real-time control based on standing time 3-3
PCS-9830A Phase Controlled Switching Device Date: 2012-09-20
3 Operation Theory
The switching time of the circuit breaker is also related to the standing time. The longer the standing time is, the longer the switching time is. By the consider of the affect, it is to compensate for the time Tdelay via the time △Trt calculated according to the standing time compensation curve pre-programmed into the device.
3.4 Adaptive Function For the adaptive function, it is mainly intended for the circuit breakers that are frequently switched, or the external parameter change influencing circuit breaker behavior can be considered as minor. The functioning principle of the compensation control is that a detected error from the target will be compensated for in the next controlled operation. There are two strategies of adaptive function, based on analog quantity detection(current/voltage) or position detection. 1.
Adaptive control based on analog quantity detection(current/voltage) In the mode, adaptation control adjusts the internally created waiting time Tdelay by detection the signals of current start instants, voltage onset instants, or current change instants from the CTs or VTs.
2.
Adaptive control based on position detection Alternatively, it also can detect the contact touch instants or the contact separation instants of the circuit breakers by the use of auxiliary contacts to adjust the internally created waiting time Tdelay. NOTE: The above examples are simplied to mainly explain the theories. In actual controlled closing/opening, other conditions need to be considered, such as the mode of busbar connection, the load characteristic and the choice of reference voltage etc.

4 Supervision and Metering
4.1 Overview Though the device is in non-operating state under normal conditions, it is waiting for a command to occur at any time and must operate for the command without fail. When the equipment is in energizing process before the LED “HEALTHY” is on, the equipment needs to be checked to ensure there are no errors. Therefore, the automatic supervision function, which checks the health of the device when startup and during normal operation, plays an important role. The numerical device based on the microprocessor operations is suitable for implementing this automatic supervision function of the device. In case a fatal fault is detected during automatic supervision, the equipment will be blocked out. It means that device is out of service. Therefore you must re-energize the device or even replace a module to make device back into service. The device also provides some auxiliary functions. All these make the device meet the demands of the modern industry requirements.
4.2 Device Self-supervision 4.2.1 Device Hardware Supervision The RAM, ROM, DC/DC and A/D elements on the CPU module are monitored to ensure whether they are damaged or have some errors. If any one of them is detected damaged or having error, the equipment will be blocked and issues a relevant alarm signal. The LED indicator “HEALTHY” will be extinguished.
4.2.2 Setting Supervision The settings are checked to ensure them to be correct and not to be modified. If the settings are checked to have any error in them, the alarm signal [Alm_Settings] will be issued and this equipment will be blocked at the same time. The LED indicator “HEALTHY” will be extinguished.
4.2.3 Supervision Alarms If there is any abnormality in the operating or firmware error detected by equipment self-diagnostic, alarm report will be displayed instantaneously on the LCD. Therefore, the default display will be replaced by the alarm report. In case there is more than one alarm has occurred, the information will be displayed alternately on the LCD. Alarm elements listed below may be displayed. Table 4.2-1 Alarm description No.

5.2 AI Module The AI module is an analog input unit. It contains three current transformers and three voltage transformer. It can transform these high AC input values to relevant low AC output value, which are suited to the analog inputs of the CPU module. The transformers are used both to step-down the currents to levels appropriate to the device’s electronic circuitry and to provide effective isolation between the device and the power system. A low pass filter circuit is connected to each transformer secondary circuit for reducing the noise of each analog AC input signal. NOTE: The rated value of the input current transformer is optional: 1A or 5A. The rated value of the CT must be definitely declared in the technical scheme and the contract. NOTE: Because the rated value of the input current transformer is optional, it is necessary to check that whether the rated values of the current transformer inputs are accordant to the demand of the practical engineering before putting the device into operation. A 24-pin connector is fixed on the front of the AI module. The terminal definition of the connector is described as below. Pin connections on the connector of the AI module:

7 Installation
In the case of equipment supplied in cubicles, place the cubicles on the foundations that have been prepared. Take care while doing so not to jam or otherwise damage any of the cables that have already been installed. Secure the cubicles to the foundations. The following shows the installation demonstration of this device.
Figure 7.6-2 Installation demonstration of this device
7.7 Electrical Installation and Wiring 7.7.1 Grounding Guidelines Switching operations in HV installations generate transient over voltages on control signal cables. There is also a background of electromagnetic RF fields in electrical installations that can induce spurious currents in the devices themselves or the leads connected to them. All these influences can influence the operation of electronic apparatus. On the other hand, electronic apparatus can transmit interference that can disrupt the operation of other apparatus. In order to minimize these influences as far as possible, certain standards have to be observed with respect to grounding, wiring and screening. NOTE: All these precautions can only be effective if the station ground is of good quality.
7.7.2 Cubicle Grounding The cubicle must be designed and fitted out such that the impedance for RF interference of the ground path from the electronic device to the cubicle ground terminal is as low as possible. Metal accessories such as side plates, blanking plates etc., must be effectively connected surface-to-surface to the grounded frame to ensure a low-impedance path to ground for RF interference. The contact surfaces must not only conduct well, they must also be non-corroding. NOTE: If the above conditions are not fulfilled, there is a possibility of the cubicle or parts of it forming a resonant circuit at certain frequencies that would amplify the transmission 7-4
PCS-9830A Phase Controlled Switching Device Date: 2012-09-20
7 Installation
of interference by the devices installed and also reduce their immunity to induced interference. Movable parts of the cubicle such as doors (front and back) or hinged equipment frames must be effectively grounded to the frame by three braided copper strips (see Figure 7.7-1). The metal parts of the cubicle housing and the ground rail are interconnected electrically conducting and corrosion proof. The contact surfaces shall be as large as possible. NOTE: For metallic connections please observe the voltage difference of both materials according to the electrochemical code. The cubicle ground rail must be effectively connected to the station ground rail by a grounding strip (braided copper). Door or hinged equipment frame
Cubicle ground rail close to floor
Braided copper strip Station ground Conducting connection
Figure 7.7-1 Cubicle grounding system
7.7.3 Ground Connection on the Device There is a ground terminal on the rear panel (see Figure 7.7-2), and the ground braided copper strip can be connected with it. Take care that the grounding strip is always as short as possible. The main thing is that the device is only grounded at one point. Grounding loops from unit to unit are not allowed. There are some ground terminals on some connectors of this device, and the sign is “GND”. All the ground terminals are connected in the cabinet of this device. So, the ground terminal on the rear panel (see Figure 7.7-2) is the only ground terminal of this device.
Figure 7.7-2 Ground terminal of this device PCS-9830A Phase Controlled Switching Device
7-5 Date: 2012-09-20
7 Installation
7.7.4 Grounding Strips and their Installation High frequency currents are produced by interference in the ground connections and because of skin effect at these frequencies, only the surface region of the grounding strips is of consequence. The grounding strips must therefore be of (preferably tinned) braided copper and not round copper conductors, as the cross-section of round copper would have to be too large. Data of braided copper strip: threaded M4, 4.0mm2. Proper terminations must be fitted to both ends (press/pinch fit and tinned) with a hole for bolting them firmly to the items to be connected. The surfaces to which the grounding strips are bolted must be electrically conducting and non-corroding. The following figure shows the ground strip and termination. Press/pinch fit cable terminal
Braided copper strip
Terminal bolt Contact surface
Figure 7.7-3 Ground strip and termination
7.7.5 Guidelines for Wiring There are several types of cables that are used in the connection of this device: braided copper cable, serial communication cable etc. Recommendation of each cable:
Grounding: braided copper cable, 2.5mm2 ~ 6.0mm2
Power supply, binary inputs & outputs: brained copper cable, 1.0mm2 ~ 2.5mm2
AC voltage inputs: brained copper cable, 1.0mm2 ~ 2.5mm2
AC current inputs: brained copper cable, 1.5mm2 ~ 4.0mm2
7.7.6 Wiring for Electrical Cables A female connector is used for connecting the wires with it, and then a female connector plugs into a corresponding male connector that is in the front of one board. For further details about the pin defines of these connectors, see Chapter 5. The following figure shows the glancing demo about the wiring for the electrical cables.

WARNING: Never allow the current transformer (CT) secondary circuit connected to this equipment to be opened while the primary system is live. Opening the CT circuit will produce a dangerously high voltage.
7.8 Typical Wiring of the Device Relevant information and sections about the modules and the connectors of this device are described in Chapter 5. Referring the relevant sections can help to wire correctly and effectively.
The power supply can be DC or AC power supply input. In Figure 7.8-1, if the DC power supply is applied, the “A~” is the positive input (PS+), and the “N~” is the negative input (PS-).
The CT currents of circuit breakers connect to the pin 601~606 on the connector of the AI module. The three phase rated voltages are from the PT of CB near to power supply, then connect to the pin 617~622 in AI module. And the voltages are used as the criterion of zero-crossing point in the CPU module.
The closing command [BI_ClsCmd] and opening command [BI_OpnCmd] are connected to the pin 402, 403 in CPU module. After the process-time, each phase controlled closing commands are output via the contacts [Cmd_ClsA], [Cmd_ClsB] and [Cmd_ClsC] to the closing coils respectively, and each phase controlled opening commands are output via the contacts [Cmd_OpnA], [Cmd_OpnB] and [Cmd_OpnC] to the opening coils respectively.
The CPU module gets the closing positions of circuits breakers via the pin 404~406, and the opening positions of circuit breakers via the pin 407~409.
The typical wiring of this device is shown as below.

It is recommended that products supplied by NR receive periodic monitoring after installation. In view of the critical nature of devices and their infrequent operation, it is desirable to confirm that they are operating correctly at regular intervals. The devices are self-supervised and so require less maintenance than earlier designs of device. Most problems will result in an alarm so that remedial action can be taken. However, some periodic tests should be done to ensure that the device is functioning correctly and the external wiring is intact.
9.1 Regular Testing The device is almost completely self-supervised. The circuits which can not be supervised are binary input, output circuits and human machine interfaces. Therefore regular testing can be minimized to checking the unsupervised circuits.
9.2 Failure Tracing and Repair Failures will be detected by automatic supervision or regular testing. When a failure is detected by supervision, a remote alarm is issued and the failure is indicated on the front panel with LED indicators and LCD display. It is also recorded in the event record. Failures detected by supervision are traced by checking the “Superv Events” screen on the LCD. When a failure is detected during regular testing, confirm the following:
Test circuit connections are correct
Modules are securely inserted in position
Correct DC power voltage is applied
Correct AC inputs are applied
Test procedures comply with those stated in the manual
9.3 Replace Failed Modules If the failure is identified to be in the device module and the user has spare modules, the user can recover the device by replacing the failed modules. Repair at the site should be limited to module replacement. Maintenance at the component level is not recommended. Check that the replacement module has an identical module name (AI, PWR, CPU, SIG, BI, BO, etc.) and hardware type-form as the removed module. Furthermore, the CPU module replaced should have the same software version. In addition, the AI and PWR module replaced should have the same ratings. The module name is indicated on the top front of the module. The software version is indicated in LCD menu “Version Info”. PCS-9830A Phase Controlled Switching Device
