Protective Relays

	Protective Relays     PROTECIVE OVER CURRENT RELAYS - The Over Current relay has been designed to protect any electrical equipment from the severity of stresses that occur during fault conditions. It also prevents excessive over loading of electrical equipment to which it is connected. Feature Precise adjustment Fast response Trip and Mains indicator Test and Reset facility Principle The output current flowing into the equipment  to be protected is sensed through a CT shunt arrangement and is compared with a reference generated internally .A relay operates whose contacts form part of control circuit of the protected equipment there by isolating its supply   Rs.1500 and  up Over Current Protective Relay

	Multifunction Protective Relays   Under Voltage  Relay - The Under Voltage  Relay has been designed to protect any electrical equipments  like compressor from burning when supply voltage falls bellow certain voltage. Feature Precise adjustment Fast response Trip and Mains indicator Test and Reset facility Principle The input voltage   is sensed by input circuit and  compared with a reference voltage generated internally .A relay operates whose contacts form part of control circuit of the protected equipment there by isolating its supply Rs.1500 and up Under Voltage Relay
