绝缘电阻

1KV cable, use 1000V or 2500V Megohmmeter to measure the resistance of conductor to earth insulation resistance instead of DC voltage endurance test.

对额定电压为0.6/1kV的电缆可用1000V或2500V兆欧表测量导体对地绝缘电阻代替直流耐压试验。

AC voltage endurance test of secondary circuit:voltage for test is 1000V,when insulation resistance of circuit is above 10M,we can use megohmmeter of 2500V for replacing,test time is 1 minute,take measures to prevent overvoltage and dielectric puncture during test.

3.10.1.3 二次回路交流耐压试验：试验电压为 1000V，当回路绝缘电阻在 10M 以上时，可用 2500V 兆欧表代替，试验时间为 1min，试验时应采取措施防止过压击穿。

If everything was ok,first test the test circuit without load in the conditions of parts to be tested not being connected,the test voltage will be increased by stages according rated voltage,each stage will be kept for 1 minute, write down the measurement values of microampere meter,then reduce voltage to zero and switch off power,make discharging for phase tested, measure insulation resistance for the other two phases.

并对被试相放电后，改接线测量另两相的绝缘电阻。在规定的试验电压下，各相泄漏电流的差别应不大于最小值的 100%。

The material of the rest of the CIRCUIT board need not have particularly high insulation resistance.

采用这种方法的优点是，电路板其他部分的绝缘电阻不必非常高。

Therefore, it's prudent to measure the insulation resistance of the test fixtures and cables periodically with an electrometer ohmmeter to ensure their integrity.

因此谨慎的做法是定期地用静电计欧姆计来测量测试夹具和电缆的绝缘电阻，以保证其完整性。
