Application of POLIPAR Metal-Oxide type arresters
>> As a result of over dose voltage and voltage collapse in the system, there exist a load loss on power supply therefore these overvoltage’s causes serious damages the system.
>> This voltage wave which exist in the system is a dangerous situation for modern industry in terms of delicate products in voltage oscillations.
>> It provides protection for control mechanism and transformers against to atmospheric and over switching voltages.
>> It provides high protection for delicate products and equipment according to surge arresters’ usage of system’s installation.
