ZC25B - 4 type insulation resistance meter test three-phase insulation. The insulation ac electric motor resistance tests measuring leakage current between the two wires. So need to put the two clip sandwiched between two wire line core. (shaking table on the grounding wire don't let it empty) wire core yellow green, A and B are measured relative phase of the insulation resistance between A to B. Red line core green B and C, the Induction motor relative phase between measurement is B to C is insulation resistance. The wire core is A and C, the measurement of the insulation resistance is A relative phase between the C. Wire core A and N, insulation resistance measurement is A relatively is zero. A line core with PE, the insulation resistance measurement is A relatively. And so on. 1 kv under low pressure, the test ZC23 or 25, two clip clamp respectively clean two conductor, from slow to quick turn the crank, about 120 r/min, maintain uniform, pointer corresponding calibration is insulation resistance magnet generator value. Such as refers to 200, is 200 ohms.
