Cable Megger Test The insulation resistance test for a cable using a megger is a continuity test, where the power of the circuit is off. for example, if the capacity of the cable is 5 amp, we cannot send current less than 5 amp or more. if we send more than 5 amp current, the cable may fail. so we test the insulation resistance. Locate the connection point of the wire or cable you want to test so you have access to the exposed conductors. clamp the alligator clip on one of the megger probes to the wire or cable, touch the other probe to the exposed conductor and press the test button. the megger will generate a current between the probes, and the meter will record the.
How To Megger Test Using This Fluke 1507 Working With Some 350 Kcmil Megger plays a critical role in helping you avoid service interruptions. that’s because megger’s cable testers find faults other devices can’t detect — whether it’s damage to the cable, workmanship failures, or cable deterioration — helping you reduce costs and maximise the security of your supply. 1. prepare the cable for testing: * make sure the cable is clean and free of debris. * remove any connectors or fittings from the cable, as these can affect the test results. 2. connect the megger to the cable: * connect the red and black leads to the cable, making sure that the insulation is not damaged. The megger insulation tester is a small, portable instrument that gives you a direct reading of insulation resistance in ohms or megohms. for good insulation, the resistance usually reads in the megohm range. the megger insulation tester is essentially a high range resistance meter (ohmmeter) with a built in direct current generator. Step 4. press the test button on megger, it will feed 3800 volts between the conductor and shield of the cable. wait for about 1 minute to settle the value of insulation resistance. initially, it will show less megger value because of the cable capacitance. finally, the value will be steady and this value is the insulation resistance of the.

Step 1: open the power termination kit cover and disconnect wires from the terminals. step 2: connect the black test lead to the grounding braid and the red test to both bus wires. step 3: perform the insulation resistance test for one minute. a passing test should be at a minimum of 20 megohms. step 4: record the test values.
