Why is understanding high-voltage oil-filled transformer bushings so critical? High-voltage power transformers are an essential component of our nation's electric grid infrastructure. Bushings are the ...

Voltage requirements are increasing, especially for the EV market. Even devices that might be considered relatively low voltage, such as display drivers, are now pushing past established baselines.

Voltage transformers (VT) are used in electrical grids for metering and/or protection purposes. The high requirements regarding their precision demand a calibration ...

Following a 70 million Euro investment, the newly extended test lab is the world’s first – and currently only – facility capable of testing ultra-high voltage (UHV) electrical grid components. The new ...
