Surge Protection

Electrical equipments are continuously subjected to abnormal voltage due to internal and external reasons. These may occur on account of lightening, switching operations, system faults and other abnormal conditions. Surge capacitors are capable of bringing down the steepness of over voltage transients that may appear across the transformers, motors and other AC line connected equipments. Unless the transients are swamped effectively, they may cause catastrophic failure of these devices. By reducing the slope of incoming surge, conventional arresters fitted in conjunction with surge capacitors, the level get truncated before operating across the insulation of a device. Surge capacitors are designed to withstand and absorb damped or oscillatory line disturbances without affecting the main frequency performance at the point of common coupling. Surge Capacitors are manufactured as per relevant IEC specifications / IS-11548/1986
