1, DC high voltage generator is generally measured, when connected to the line, the first line of the connected sample is vacant, rise to the test voltage, read the corona and stray current I' when the air test, and then connected to the test The product rises to the test voltage and reads the total current I1. Sample leakage current: I0=I1-I′
2. When it is necessary to accurately measure the leakage current of the test object, a high-voltage shielding microammeter should be connected in series in the high-voltage loop; after the wire is wound tightly for several turns, it is connected with the shield of the high-voltage lead wire.
3, the zinc oxide arrester, magnetic discharge arrester and other test products can be separated from the ground, can also be used at the bottom of the sample (ground potential) in series ammeter to measure, but it must also use shielded wire; To eliminate the influence of the surface leakage current of the test piece, a bare bare copper wire can be used to connect with the shield at the ground potential end of the test piece for a few turns.
4. After the test is completed, step down and adjust the positioner back to zero. Then press the green button to cut off the high voltage and turn off the power switch.
5. For small-capacity samples such as zinc oxide surge arresters, discharge is usually performed through a resistance meter and the time is very short. For large-capacitance test items such as cables and motors, it is generally necessary to wait until the voltage of the test sample self-discharges to less than 20% of the test voltage, and then discharge through the discharge bars. After the sample to be fully discharged and the grounding wire is hung, it is allowed to remove the high voltage lead and replace the wiring work.
In the course of use, it is found that the red light is off, the green light is on, and the DC high voltage is down, which is the related protection action. At this point, follow these steps:
1, will adjust the piezoelectric device back to zero.
2, turn off the power switch, panel lights are not lit.
3 After one minute, the low-voltage capacitor in the standby is fully discharged and the power switch is allowed to turn on again. After the no-load test is resumed and the situation is ascertained, the test may be boosted again.
