REACTOR SWITCHED BY THYRISTORS ACTING AS A DEVICE FOR AVOIDING FERRORESONANCE IN INDUCTIVE POWER TRANSFORMERS.

摘要

The present invention avoids damages to inductive power transformers and related electric equipment, due to ferroresonance in an electric substation. The invention uses a reactor switched by thyristors, which is a device included in flexible systems of alternate current transmission. The reactor switched by thyristors for avoiding ferroresonance in inductive power transformers comprises a valve of thyristors connected in series to a linear inductance, where the thyristors interrupt and connect the inductance to the circuit for avoiding the ferroresonance.
