Electronic Error-Compensation of a Voltage Transformer
Parameswaran Sankaran, Pradeep Mohan Kumar Kanagasabapathy, Vempati G. K. Murti · IEEE Transactions on Instrumentation and Measurement · 1979
It is shown with supporting experimental results that the error of a voltage transformer supplying a burden can be brought down to the value on open-circuit, using an amplifier whose output is approximately equal to the error voltage. The scheme permits the normal requirement that one end of the burden be earthed.
