System for Transformer Protection Layer citivos - Voltage and improve the Transient Response

摘要

Protection device of Voltage transformers and capable of Modification of the Transient Response.It consists of a control Circuit that detects the onset of relaxation and subarmonicas oxidation or desparacion of tension and gives rise to a trigger Signal to a load circuit in the secondary side of the Transformer; the load is divided and its disconnection is done so Q In each EU semiciclo occurs a decrease of load.The control Circuit comprises a Filter Circuit, an amplifier circuit, Rectifier, a Timer and a bistable Circuit.
