Instrument use

• Voltage measurement:
  1. The L end of the test line of the instrument is connected to the tested product, and the E end is grounded.
  2. Turn on the instrument to check the actual measured voltage, and the instrument can automatically distinguish between DC and AC.
  3. Regardless of whether it is DC or AC, if it exceeds 10V, check again whether the circuit breaker under test is disconnected.

• Measure the absorption ratio DAR:
  4. Choose a measurement time longer than 1 minute
  5. Select the appropriate voltage and start.
  6. The instrument automatically records the resistance values ​​ of 15S and 60S, and
  calculates the absorption ratio after 60 seconds.
  Absorption ratio calculation method: DAR= R60/R15;

• Measure polarization index PI:
  1. Choose a measurement time longer than 10 minutes
  2. Select the appropriate voltage and start.
  3. The instrument automatically records the resistance values ​ of 15S, 60S, and 600S, and calculates the polarization index after 600 seconds.
  Polarization index calculation method: PI= R600/R60;

• DD test

This test is suitable for the diagnosis of multilayer insulation. It is a good way to judge the defects in multilayer insulated objects by measuring the discharge current value and the capacitance value of the measured object 1 minute after the completion of the test.
DD value = current value (mA) 1 minute after the test is completed / voltage value (V) when the test is completed / capacitance value (F)

This criterion is the target value, and may require users to adjust or change the test method developed for testing the high-voltage generators of European power stations.

• Precautions for test wiring
  1. Confirm that the tested product is safely grounded, and the tested product is not live.
  2. Confirm that the E terminal (grounding terminal) of the meter is grounded.
  3. Use of G end (protection ring) (this machine is shielded on the low voltage side)
  When measuring high insulation resistance, a conductor protection ring should be put on the surface between the two measurement terminals of the test product, and the conductor protection ring should be connected to the G terminal of the meter with a test wire to eliminate the leakage current caused by the surface of the test product. The measurement error ensures the accuracy of the test. Especially when verifying the instrument, the G terminal should be connected to the G terminal of the resistance box to ensure normal verification.
