The first case study is about an on-site measurement on a 66kV to 132kV reference VT. The secondary winding has two taps for adapting the voltage ratio between 132kV/√3:110V/√3 and 66kV/√3:110V/√3.
The Bonneville Power Administration’s high-voltage lab in Vancouver, Washington, U.S., is a one-of-a-kind asset. It features a cascade transformer that can produce up to 1.1 million V, which allows ...
