Commissioning tests distribution protection

Secondary and primary testing – Practice workshop with Megger SVERKER 900

Seminar description:

Tests during commissioning or after modifications of medium-voltage switchgear panels require to verify the entire chain from the instrument transformers via the protection to the circuit breaker trip.

This seminar teaches the basics of CTs and protective relays as well as primary and multiphase secondary testing techniques. In the exercise parts, tests are practised practically.
