Description
Product details
The relay senses the Insulation resistance of any unearthed system, Mostly suitable for DC Earth leakage protection for any equipment's like Switch boards, Rectifiers, Battery Chargers. It senses Resistance between Positive & Negative Terminals of DC System & Earth. The leakage current if any will be dependent on the Insulation resistance value between respective terminals, Higher the resistance , lower is the leakage current & vice versa. Lower resistance results in to loss of life or damage to equipment. PROTIME’s N22-IMR senses insulation resistance using Resistor Bridge principal & energizes relay when Resistance value goes below the value selected on the dialThe Relays are provided with user settable (0-10Sec) time delay . The relay is paired with suitable Sensor as per system voltage, & has a provision of connecting External Leakage resistance meter (Analog). Center infinity meter can be provided with calibrated scale to measure IR.
