Abstract

Device for protection of capacited voltage transformers and modification of the transitory response. It consists of a command circuit that detects the appearance of relaxation and subarmonic oxidation or the disassembly of the voltage and that gives a signal of trigger to a loading circuit in the secondary of the transformer; this load is divided and its disconnection is carried out so that each semicicle will produce the same load decrease. The command circuit comprises a filter circuit, an amplifier-rectifier circuit, a timer and a bistable circuit. (Machine-translation by Google Translate, not legally binding)
