LCM500 Leakage Current Monitor User Guide



Chief Safety Hazards for the LCM500 These chief safety hazards accompany the use of the LCM500: • • •



Electrical hazards are always present in substations. Always keep the LCM500 and yourself within published safe-approach distances to energized conductors. Thunderstorms: Never operate the LCM500 when there are thunderstorms in the area. Switching overvoltages: Never operate the LCM500 when switching overvoltages are likely to occur.



Overview of this User Guide This user guide explains how to use the hardware and firmware of the Doble LCM500 Leakage Current Monitor for metal oxide surge arresters. The LCM500 can test the condition of all makes of metal oxide surge arresters (MOSAs) that are mounted on an insulated base. It cannot test surge arresters that are directly grounded to the system ground of the substation, with no separate ground lead. The firmware discussed in this guide is version 1.28 or later.



Who Should Read This Guide This guide is intended for anyone using the LCM500. It is assumed that you are familiar with professional standards and safety practices.

Requirements for Condition Monitoring



72X-0058-01



Rev D



Before you begin condition monitoring of MOSAs, ensure that: • The arrester base is insulated from the ground. For example, the arrester can be mounted on an insulated base. • The arrester is grounded through a single grounding wire, preferably insulated. • There are no thunderstorms in the vicinity.

Step 1: Ground the System



A special plug on the LCM500 has ensures that both the power supply cable and the grounding wire have a good connection to the instrument. Follow the grounding instructions that are appropriate for your location and power supply: • Indoors—Connect the power supply cable to a wall socket, making sure that the ground pin in the socket is connected to the common grounding system (Figure 2).



Figure 2 Grounding Connection for Laboratory Measurements • In the field—Connect the grounding wire supplied with the LCM500 to the substation grounding system (Figure 3).



Figure 3 Grounding Connection for Field Measurements



Step 2: Install the CCT500



The CCT500 connects wirelessly to the LCM500 main unit. If the CCT500 is being installed for long-term monitoring, it is advisable to shield it against rain and snow. To install the CCT500: 1. Press the On button on the front of the CCT500. The probe diode indicates the probe status. See Table 7 on page 37 for information about diode behavior.

2. Clip the CCT500 on the grounding wire of the arrester: • Be sure that the jaws of the clip-on are properly closed. • If a surge counter is present, place the CCT500 between the arrester base (item 1 in Figure 4) and the surge counter (item 2) to avoid the influence of the surge counter ground Figure 4 shows one typical setup; your installation may vary.

Step 3: Install the Field Probe



72X-0058-01



Rev D



The Field Probe (FP500) consists of 2 metal disks, which are antennae, and one measuring unit. There is a keyhole in the center of each disk; the two keyholes are of different sizes.

5/2018



LCM500 Leakage Current Monitor User Guide



Positioning the Field Probe Correctly



For best results, place the FP500 below the base of the surge arrester, within 1 m of the base. If the FP500 is placed too far from the arrester base, noise from other phases may create measurement error. In a few instances, you may need to place the FP500 in a different position. In those situations, identify the neighbor phases, metal structures, and electrical field density, and place the FP500 in the most advantageous position possible. For consistent measurements, always place the probe in the same position when you perform a series of measurements. It may be helpful to use a hot stick or Field Probe Rod to operate the FP500.



Procedure



To install the FP500, consult Figure 5 and follow these steps: 1. Slide the disk with the large keyhole over the top of the probe and down to the measuring unit (item 1 in Figure 5). Firmly pull the disk sideways so that the small end of the keyhole slides into the narrow groove in the shaft. 2. Slide the disk with the small keyhole hole over the top of the probe. Firmly pull the disk sideways so that the small end of the keyhole slides into the slot at the end of the shaft (item 2 in Figure 5).

4. Do one of the following: • Using the rod fitting adaptor supplied with the LCM500, put the FP500 on the optional Field Probe Rod made by Doble. • Put the FP500 on an adequate rod supplied by the substation. 5. Stand under the overhead line. Raise the FP500 to the correct height, within 1 m (3 ft) of the arrester base. Make sure that the antenna disks float electrically and do not touch any parts of the surge arrester. Keep the FP500 in this position during measurements.

3. Overview of the LCM500 This chapter provides a detailed overview of the LCM500 system. It contains the following sections: • • • • •



“Introduction” on page 29 “Unpacking and Inventory Check” on page 32 “Hardware Overview” on page 33 “LCM500 Power Sources and LED Indicators” on page 34 “LCM500 LED Power Indicators” on page 35



Introduction



The LCM500 performs in-service measurement of the resistive leakage current of gapless metal-oxide surge arresters (MOSAs).



Required MOSA Configuration



The MOSA to be tested must be mounted on an insulated base. Surge arresters that are directly grounded to the system ground of the substation, with no separate ground lead, cannot be tested by the LCM500.



Factors Affecting MOSA Condition



Information about the resistive part of the leakage current provides insight into the condition of the metal oxide surge arrester. An increased resistive leakage current indicates a higher risk of breakdown of the MOSA. In normal service, MOSAs are exposed to such stresses as normal operating voltage, temporary overvoltages, switching overvoltages, lightning overvoltages, and external pollution. Separately or in various combinations, these stresses may cause an increase of the resistive component of the continuous resistive leakage current through the arrester. This increase may exceed the critical limit and cause arrester failure.



Two Types of LCM500 Testing



72X-0058-01



Rev D



The LCM500 system can be used in two ways: • For periodic checks on regular or trend-dependent basis. • For short-term monitoring of an arrester that has given suspicious readings.

A Four-Part System



Normalized Data



72X-0058-01



Rev D



The LCM500 system consists of four parts: • LCM500 main unit—Instrument that gathers information from the CCT500 and FP500 wireless probes. The LCM500 calculates the crest value of the resistive leakage current component. • CCT500—Wireless current transformer that measures the total leakage current through the MOSA’s ground lead. • FP500—Wireless field probe positioned near the base of the arrester. The FP500 provides information about the voltage stressing the arrester: the 3rd harmonic capacitive current component caused by harmonics in the system voltage. • LCMViewer—Windows® compatible program that prepares measurements and analyses and administers resistive leakage current data. Using arrester system data, ambient temperature, and operating voltage, the LCM500 automatically normalizes resistive leakage current (lr corr) data to a standard ambient temperature (20 °C/68 °F) and operating voltage (70% of the arrester’s rated voltage). The normalized data make it easy to compare measurements performed under different conditions.

LCM500 Leakage Current Monitor User Guide



Each measurement can be connected to a specific arrester ID in LCMViewer. When the instrument database and LCMViewer are synchronised, the measurement is stored in the correct LCMViewer location.



Measurement Method



The LCM500 measuring method is based on the principle of third-order harmonic analysis of the leakage current with compensation for harmonics in the system voltage. During field measurements, the LCM500 displays these values: • Peak value of normalized (corrected) resistive leakage current or third harmonic current • Peak value of non-corrected resistive leakage current • Peak value of total leakage current • Ambient temperature • Operating voltage (phase-to-phase voltage) • Percentage of third harmonic content in the overhead line voltage All values except third harmonic values can be saved to the LCM500 database and loaded into the LCMViewer application.



Note: Third harmonic values can be displayed. They cannot be saved. You can use the resistive leakage current data in several ways to evaluate arrester condition: • Perform a trend analysis: Compare the normalized resistive leakage current level to previous measurements on the same arrester to reveal significant changes over time. • Compare the normalized resistive leakage current to the maximum recommended level specified by the arrester manufacturer. • Compare the normalized resistive leakage currents from one arrester to the same test results for arresters of the same type or make, or for arresters in the same region.

No light



No connection between charger and docked probe. If the probe is left in the charging station for more than 48 hours, the overvoltage protection inside the battery disconnects the battery from the charger circuit and the diode is extinguished. This safety precaution protects the battery from overheating. To reconnect the battery and the charger, take the probe out of the charging station, switch the probe on and off, and replace it in the charging station. The LED now indicates the correct status again.



The LCM500 main unit communicates over a radio link with the FP500 and CCT500. The radio range varies because, in different parts of the world, the system uses different radio modules to satisfy local regulations for wireless communication.

C. Influence of Temperature and Operating Voltage The resistive leakage current depends on the arrester temperature (in practice the ambient temperature) and the operating voltage. Table C.1 shows calculations for a specific MOSA, illustrating the importance of a condition monitoring system that takes account of theses two parameters. The calculations are done for four different ambient temperatures and three different operating voltages. If the temperature and voltage simply are not taken into account (uncorrected values), the measured value of the resistive leakage current strongly varies (in this specific case from 31 to 112 µA). Thus, uncorrected leakage current data should not be trusted to give reliable information about the arrester condition. However, by using arrester system data and measuring the ambient temperature and operating voltage at the same time as the condition monitoring is performed, it is possible to recalculate the leakage current data to a common reference (20 °C and U=0.7Ur). The resistive leakage current values will then be approximately the same independent of the test conditions (see corrected values in Table C.1). In other words – by taking account of the ambient temperature and operating voltage, measurements performed under different conditions can be directly compared, and the measured values will be a reliable indicator of the arrester condition.
