Electronic compensation of inductive voltage dividers and standard voltage transformers
(IEEE, 1999)
A new compensating system is proposed to reduce the ratio error and the phase error of inductive voltage dividers and standard voltage transformers, operating at no load. An electronic amplifier reduces the input current, ...
Electronic based high-voltage measuring transformers
(IEEE, 2002)
A new electronic system to assist high-voltage measuring transformers is proposed. This system compensates the voltage drops in the series impedances of the transformer, which are the main cause of errors at power frequency. ...
Electronic compensation of inductive voltage dividers and standard voltage transformers
(IEEE, 1998)
A new compensating system is proposed to reduce the ratio error and the phase error of inductive voltage dividers and standard voltage transformers, operating at no load. An electronic amplifier reduces the input current, ...
