Abstract :
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, which is the main cause of error in low-frequency applications, while at the same time the input impedance is greatly increased
