Electronic compensation of voltage transformers
Daniel Slomovitz · IEEE Transactions on Instrumentation and Measurement · 1988
A method for compensating ratio errors and phase displacements of measuring voltage transformers by a simple electronic circuit is introduced. This electronic compensator keeps the primary winding isolated from the secondary winding, so that it can be applied to voltage transformers in any kind of use. It also works with large load power variations. With this compensation, smaller and cheaper transformers may fulfil the same accuracy and power output requirements as larger transformers.>
