WebG.K. Bayne. The megohmmeter, or megger, is a measuring device that tests high electrical resistances. Typically these measurements are made on electrical wires and motor windings to test the insulation value of the wires. The prefix "meg" describes a numerical value of 1,000,000. In the case of an ohmmeter that value is also described in ohms. WebDec 6, 2010 · Test your megger, leads apart and leads together. Use paper and scribble with a soft lead pencil on the paper and megger the paper. Yopu'll have to play with this, with different amounts of lead and scribbles you'll get varying readings. Be careful doing this under a smoke detector. Use a good case.

WebTouch test probe to shunted compressor terminals. Depress test button on test probe (or on meter) for test duration period (60 seconds). Record resistance value and terminal temperature. Remove shunt across compressor terminals and restore to proper electrical connections. Place compressor in operation for 5 or 10 minutes. WebThe armature circuit resistance can then be calculated by using the following basic steady state DC motor equation: E = I x R + (Ke x w), where. E = applied voltage. I = current. R = armature circuit resistance. Ke = voltage constant. w = speed (omega) Since speed = 0 with the armature locked in place, the back emf voltage (Ke x w) = 0 and the ...
