  • Page 6: An Introduction To Dielectric Withstand Testing With The Ht-5000P

    Currents of as little as 5 mA at 120 volts can cause death, and the HT- 5000P can generate up to 10 mA AC and 5000 volts, and 5 mA DC at up to 6000 volts. The HT-5000P has been designed to minimize exposure to high voltages.

  • Page 7: Safety Techniques

    If the lead is not properly connected, a dielectric withstand test failure may energize exposed dead metal of the equipment being tested. Additionally, the HT-5000P may not recognize the failure. The test will continue for its normal length of time, and the HT-5000P may show a "PASS".

  • Page 8: Sporadic Leakage Current Failures

    If the leakage current adjustment of the HT-5000P is set to 10 mA AC and almost all examples of the model being tested are still failing, the primary circuit capacitance of the equipment may be too high to allow the AC dielectric withstand test to be used.

  • Page 9: High Voltage Dielectric Withstand Test Failures

    The HT-5000P is designed to discharge the high voltage after completion of the dielectric withstand test. The equipment being tested should remain connected to the HT-5000P until the voltage has discharged to a safe level to protect the operator and to ensure that there is no energy stored in the...

  • Page 10: Introduction And Specifications

    If a failure is encountered, the high voltage is immediately shut down, a buzzer sounds, and any voltage stored in the equipment being tested is bled off by a resistor bank in the HT-5000P. The voltage discharge progress is shown by the front panel meter.

  • Page 11: Specifications

    Total Defeat. Full voltage is produced at the output immediately. Test will continue only as long as the TEST button is held in. The HT-5000P will not shut down on a leakage or dielectric failure, but the front panel Excess Leakage or Hipot Fail lights will indicate a failure. The Hipot Pass light will not light at the completion of a successful test.

    6. Push the TEST button. 7. The HT-5000P tester will conduct a test. The meter will read a voltage, hold, and return to zero. During the test, the voltage can be adjusted using the Voltage Adjustment knob. At the end of the test, the Full Voltage, Hipot Pass, and RESET switch indicators should be lit.

    RESET button on the front panel. Test Procedure Example: Connect the HT-5000P to a correctly rated source of supply and turn the power switch to the I or ON position. Push the RESET button. The yellow TEST indicator should light, indicating that the HT-5000P is ready to test.

  • Page 20: Test Results

    Red LED/Buzzer: Any red LED/buzzer test result means the equipment being tested failed a test phase. The equipment should be set aside, reworked and retested with acceptable results before it is shipped. General interpretations of test failures are included in Section 1, "Using the HT-5000P V2 Dielectric Withstand Tester".

    14. Turn Off the HT-5000P tester. 15. The voltage can be verified by turning on the HT-5000P, running a test, and using the 1000:1 voltage probe to check the meter at different voltages. If the voltages are not within +/- 2% at each voltage, the voltage calibration must be performed again starting at step 1 above.

  • Page 25: Current Calibration Adjustment

    Turn the Voltage Adjust on the front panel to minimum (counterclockwise). Connect the output of the HT-5000P through a 60K ohm, 100-watt high voltage resistor in series with a calibrated DMM capable of measuring 10.0mA AC and returning to the Return jack on the front panel of the HT-5000P.
