Attach the high voltage lead to one of the isolated circuit phase conductors. Switch on the HIPOT Tester. Set the meter to 1000 Volts or pre decide DC Voltage. Push the “Test” button on the meter and after one minute observe the resistance reading.
What is AC Hipot test?
A dielectric strength test, commonly called a hipot test, dielectric withstand, or high potential, is a stress test of the insulation of a device under test (DUT). Such a test applies a voltage to the DUT that is much higher than normal operating voltage; typically 1000V AC plus twice the normal operating voltage.
What is the purpose of Hipot test?
Hipot test is the most common type of electrical safety test. Designed to verify that the insulation of a product is adequate enough to withstand high voltage. Performed by stressing the insulation of the product far beyond what it would encounter during normal use.
What is a HAL tester?
The HAL 103 is a comprehensive tester capable of performing dielectric strength, earth/ground bond and DCIR tests.
Is AC Hipot testing destructive?
WHY DC HIPOT TESTS ARE NOT DESTRUCTIVE. One advantage of the DC Hipot test is the following: Although the test voltage can be high, the energy available to be discharged as an arc is small. Thus, arcs from a DC Hipot test are not destructive if the test is done properly.
What is an earth bond test?
The earth bond test measures the resistance of the earth from the pin of the mains supply plug to the earthed body of the appliance and indicates how good the connection is. The pass value is normally (0.1 + R) Ohms where R is the resistance. If a reading is less than 0.1 Ohms then the results is a PASS.
How do you check for current leakage?
Measurement of leakage current to ground Test single-phase circuits by clamping the phase and neutral conductor. The measured value will be any current flowing to ground. Test three-phase circuits by clamping around all three-phase conductors.
