Abstract [en]

A parallel injection of short circuit current and transient voltage to medium and high voltage circuit breaker (CB) by a synthetic model is studied. Transient recovery voltage is created by a capacitor bank and is applied to CB. Also short circuit current is supplied by a 20/0.765 Kv short circuit transformer. Texas DSP is used as controller and programmed in code composer.To test of circuit breakers by synthetic test equipments, an accurate control system can satisfy the test criterion. An optical triggered spark gap has been used to interrupt short circuit current and to initialize of transient recovery voltage (TRV) that is applied across the contacts of circuit breaker. Modeled results are verified by a laboratory based synthetic test system. Test object CB is a 24 Kv, 25 KA with vacuum type chamber. To find a desired sequence to open/close of backup- test object and auxiliary circuit breakers within appropriate time to inject of recovery voltage is main goal of the presented paper. Modeling and simulation has been done in MATLAB software. Test procedure has been done under IEC 62271-100 , 62271-101.
