If the surge arrestor is out of service, it causes short circuit in the system. When surge arrestor separator is not used, this short circuit cause the activation of the circuit breaker and blackout of the energy of the system. Surge Arrestor separator prevents energy blackout by cutting grounding connection of the surge arrestor that is out of service. Activation of the surge arrestor separator, in other words cutting the grounding connection means that the Surge Arrestor has lost its function and must be replaced. Structure and Mode of Operation; When the surge arrestor loses its function, separator responds quickly to the current flow on it. Voltage decreases on the resistances of the separator and the capsule explodes by means of the arc occurring in the small opening inside of it and separates grounding connection of the surge arrestor.

Atmospheric events and on-off surges in the system cause formation of extreme voltages in electricity networks. ELOPAR surge ARRESTORS are designed to protect distribution transformers, engines, work machines and medium voltage cables against extreme voltages in the best way. Advantages of Elopar Polymer Surge Arrestors are; - Low Protection level - No danger of explosion - Long protection distance- High energy input capacity Resistant to aging - Stable characteristics - Polymer housing- Resistant to contamination - Safe assembly- Maintenance-free - High support resistance- Easy to use - Creeping distance is over 25 mm/kV- Light Structure and Mode of Operation; Metal oxide surge arrestors do not contain gaps but contain metal oxide blocks that are placed into a polymer body impermeably. These blocks carry variable resistance feature. In other words, they become conductive as the voltage rises. In case of temporary over voltage, current flows over surge arrestor so that such devices or cables are protected. These surge arrestors not only have a very good mechanical strength, but also have very good dielectrically smoothness in all surfaces. Furthermore, they have high resistance against contamination arising from atmospheric conditions under the heaviest operating conditions. ELOPAR Polymer Surge Arrestors are manufactured according to TS EN 60099-4 (IEC 60099-4) standard in order to perform this task in the best way. Type tests have been performed at ICMET CRAIOVA High Power Laboratory and it has passed from all tests successfully. - Surge arrestors must be as close as possible to the device to be protected. - Surge Arrestor grounding must be the same with the system grounding
