The Motwane Manufacturing Company
High contact resistance values are a definite cause of the failure or less than optimal performance in a wide variety of electrical devices. Contact resistance testing is therefore most critical to measure the resistance of electrical connections in switching devices, circuit breakers, isolators, busbars, relays, joints, connectors, cables, and cable joints. The device helps to find destructive or corroded contacts and hence protects substation devices from damage.

Earth Contact Resistance Tester
-
SCR ELEKTRONIKS have developed an equipment namely Earth Contact Resistance Tester to test the appliance. To ensure the safety of operator it is essential that the Earth path (connection) should offer minimum impedance to by pass short circuit Current to Earth. This is ensured by measuring Resistance of the Earth path by passing heavy Current say 25 A. The Earth Contact Resistance Tester essentially comprises of a Variable Current source with digital Ammeter to measure the Current supplied. The Voltage drop across the Earth path is measured with a digital Voltmeter. Optionally for a particular Current (25 A) the meter can be calibrated in terms of Resistance. A timer is provided to switch off the Current after the Set Time.
