When testing with Primary Test Manager, observe the safety rules in this chapter and all relevant safety instructions in the technical documentation shipped with the test systems. If you do not understand some safety instructions, contact OMICRON electronics before proceeding. Before connecting any test leads to a test object, always observe the five safety rules: •
Disconnect completely
•
Secure from reconnection
•
Verify that the installation is dead
•
Carry out grounding and short-circuiting
•
Provide protection against adjacent live parts
Operator Qualifications and Safety Standards Working on the high-voltage equipment can be extremely dangerous. Consequently, only qualified, skilled, and authorized personnel is allowed to test with Primary Test Manager. Before starting to work, clearly establish the responsibilities. Personnel receiving training, instructions, directions, or education on Primary Test Manager must be under constant supervision of an experienced operator while working on the high-voltage equipment.

Introduction
1
Introduction Primary Test Manager is a management tool for testing primary assets such as power transformers with the OMICRON test systems. Primary Test Manager provides a computer interface to the test set, controls the automated test procedures, and facilitates testing of power transformers by guiding you through tests. With Primary Test Manager, you can manage locations, transformers, and jobs, and then perform measurements by just pressing the I/0 button on the front panel of the CPC 100 test system. Afterwards, you can retrieve exhaustive test reports. Primary Test Manager runs on a computer or a notebook, and communicates with the test set through the Ethernet connection. With Primary Test Manager, you can make all relevant tests for the two-winding transformers, three-winding transformers, and autotransformers.

Application Data and its Backup The application data is stored in the following directory: %ALLUSERSPROFILE%/Application Data/OMICRON/PTM/Data. We strongly recommend to back up this directory at regular intervals (for example, scheduled daily) depending on the intensity you are working with Primary Test Manager. Since this directory contains the application data, files must not be directly modified to avoid data inconsistency. Note: %ALLUSERSPROFILE% is an environment variable, pointing, for example, under Windows XP to C:\Documents and Settings\All Users and under Windows 7 to C:\ProgramData\OMICRON\PTM\Data.
