Diagnostic measurements on instrument transformers

December 27, 2017

Within the electrical supply system instrument transformers (current and voltage/potential transformers) belong to the lower-priced assets. However, a severe instrument transformer failure can cause serious danger to people and significant damage and costs to the surrounding equipment, putting the overall system at risk.

Our paper of the month gives a classification and overview of the most common diagnostic measurements on instrument transformers used to assess their condition and reliability. It also describes the possible failures which can be revealed by the measurements and shows the importance of conducting regular diagnostic tests.

Enjoy reading and watch out for our paper of the month regularly!
