On-site Partial Discharge Measurement and Localisation on a Power Transformer
Power transformers, a key element of the electrical grid, are subjected to different levels of electrical, thermal, mechanical, and chemical stress during service. To ensure reliab
Testing of Current and Voltage Transformers
Current and voltage transformers are vital components in an overall protection technology system. It is therefore important that the transformer is not just seen as a one-off piece
Medium Voltage Circuit Breaker Condition Assessment
In an effort to ensure N-1 network security, grid operators keep looking for equipment that helps them fulfil this requirement. Within the medium voltage power grids of the world,
Why is it Important to Demagnetize a Transformer’s Core?
Whenever a power transformer is isolated from the power system, residual magnetism remains in its core due to a phase shift. Residual magnetism also remains after a DC voltage has
