Protective Relay and Protection System Commissioning

Commissioning engineers often work under difficult time constraints. The availability of equipment is essential for adhering to these time schedules. Time-saving test automation for standard test procedures is also a must for meeting the deadlines of a time sensitive environment.

In addition to classic protection tests, commissioning engineers have to verify the correct operation of all the statuses and interlocking elements in a substation. Other typical tasks that have to be performed include SCADA annunciations checks, burden measurement, CT/VT polarity checks, wiring checks, logic scheme tests (with event recording) and plausibility checks for CT/VT with primary injection. Recording transformer inrush-currents can also be an important task for verifying whether or not the protection has been set correctly.

Our reliable, easy-to-use, lightweight and robust CMC test sets and our Test Universe Software are ideally designed to meet the demands of commissioning engineers. We also offer a wide range of accessories including equipment for GPS synchronized testing.
