Electronic error reduction system for clamp-on probes and measuring current transformers
(IEEE, 2000)
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, ...
Influence of double excitation AC/DC in the reactive power demand of 3-phase transformers
(IEEE, 1999-12-01)
In this work it is discussed the performance of the reactive power demand in three-leg transformer core and three-phase transformer bank, under different conditions of AC/DC double excitation. In order to analyse the ...
