Parametric Analysis of Surge Test Circuit for Auto Recloser to Resolve Experimental Difficulties

Automatic circuit reclosers or fault interrupters are self-controlled device for making, carrying, and automatically interrupting and reclosing an alternating-current circuit. The automatic circuit recloser consist an assembly of control elements required to detect over currents and control the recloser operation. These equipment capability to survive fast lightning induced surges have to be verified by simulated surge arrester operation test. This paper discusses about the International standard stipulated test requirements and practical difficulties encountered while performing the test. This paper also presents the PSPICE based parametric analysis and the effectiveness of the variation in each component of test circuit on the parameters of test voltage and current waveforms.
