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 ...

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, ...

This paper proposes the application of computational intelligence techniques to assist complex problems concerning lightning in transformers. In order to estimate the currents related to lightning in a transformer, a neural ...

Purpose: This study aims to validate the content of an instrument which identifies the organizational, sociocultural and technological characteristics that foster digital transformation (DT) in higher education institutions ...

Instrument transformers (IT) are used to reduce current or voltage values of the electric power system (EPS) to values which are tolerated by the measurement, control and protection instruments, without changing its nature. ...
