Electronic system for increasing the accuracy of in-service instrument-current transformers
(IEEE, 2002)
An electronic compensator of ratio errors and phase-displacements is proposed for in-service transformers. Neither an auxiliary winding nor auxiliary core is needed; and large variations of the load connected to the secondary ...
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 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, ...
The use of current transformers for noise detection due to sparking in insulators strings in high voltage transmission lines
(2010-12-31)
In a general way, in an electric power utility the current transformers (CT) are used to measurement and protection of transmission lines (TL) 1 The Power Line Carriers systems (PLC) are used for communication between ...
