An Introduction to Dielectric Withstand Testing with the HT-5000P ac/dc 200mA

The dielectric withstand test is a test which is recognized by safety agencies worldwide as a valid criterion of safe assembly of end-use equipment. The HT-5000P ac/dc 200mA is designed as a research instrument to determine the dielectric properties of component assemblies of end-use equipment. It applies a high-voltage potential between Output and Return test leads and monitors Leakage Current, and watches for Dielectric Breakdown during the test. To aid in testing, the HT-5000P ac/dc 200mA can be configured with or without a test duration timer, and can be set to deliver high voltage after an arc has been detected to pinpoint an area of arcing.

The dielectric withstand test involves high voltage, and caution should be exercised when using the HT-5000P ac/dc 200mA. The Return Receptacle on the front panel is connected to ground potential, and setups should be designed with this in mind, to guard against the operator contacting high voltage. Always make sure the return lead is firmly connected.

Leakage Test

The HT-5000P ac/dc 200mA leakage test uses a separate low-frequency circuit to detect excessive current between the Output and Return receptacles on the front panel. There is not a specific leakage current level pass/fail requirement at this time for most equipment. However, higher than normal leakage current on a particular sample may indicate an assembly, and or a component problem in the circuit.

The leakage current is also monitored by the HT-5000P ac/dc 200mA to ensure that excessive leakage does not keep the tester from developing full voltage required for the high voltage test. The HT-5000P ac/dc 200mA will provide full voltage at any leakage current level up to 200mA. Set the acceptable leakage current limit using the Shutdown Limit Potentiometer on the front panel.

If the green Full Voltage indicator lights and the test continue, the leakage current was below the acceptable limit. If the red Excess Leakage indicator lights, the buzzer sounds, and the test is terminated; the leakage current was above the acceptable limit.

High Voltage Dielectric Withstand Test

This test checks for insulation system breakdown’s by applying a high voltage between the Output and Return receptacles on the front panel. The HT-5000P ac/dc 200mA uses a separate high-frequency circuit to detect arc breakdowns.

Set the test duration with the Timer Control Potentiometer on the front panel. The test time is counted from the time the Full Voltage indicator is lit to the completion of the test. The Timer Control Switch must be set to ON, or the HT-5000P ac/dc 200mA will test only while the Test Button is pressed. The minimum test time is one second regardless of the setting of the Timer Control Switch.

If the green Hipot Pass indicator lights, the test cycle has been successfully completed, meaning there was no dielectric breakdown. If the red Hipot Fail indicator lights, a breakdown arc has been detected.

High Voltage Discharge

The HT-5000P ac/dc 200mA has an internal circuit designed to remove the high voltage, after completion of the dielectric withstand test. The HT-5000P ac/dc 200mA should remain connected to the circuit until the front panel meter shows that the output voltage has dropped to a safe level.
