Ground bond test procedure

FOUR WIRE MEASUREMENT (KELVIN METHOD ) FOR GROUND BOND TEST. When measuring low value resistances (for the ground bond test for instance), an important error . Electrical safety testing has historically been one of the most misunderstoo misapplied and misinterpreted inspection functions administered by manufac- turing companies. Some manufacturers have looked upon safety testing as an extraneous set of procedures that must be performed to satisfy some safety.

First, the ground bond test is run to ensure that the grounding circuit is sufficient for the product.

Stand back from the DUT and press the TEST button.

Set the Hipot test to the parameters listed above.

Line Leakage Test , Earth Leakage Current . Measurement of Leakage Current 23. Introduction to Global Safety and Directive. The purpose of ground protection test is for protecting users from electrical hazards as touching equipment when unsuitable current is . Why are electrical products grounded?

Determine size of ground grid system and calculate length of test leads required. Site Testing Fall of Potential. IEC9TECHNICAL REPORT – METHODS OF MEASUREMENT OF TOUCH- CURRENT AND PROTECTIVE CONDUCTOR CURRENT.

GROUND CONTINUITY TEST (also called ground bond test , bonding test ). Test at Multiple locations across the site. I was asked to verify that the receptacle ground connections were less than ohms from nearby building steel uprights – the construction electrical bonding . Ground Electrode System Components. These tests include the ground bond (or continuity) test , dielectric withstand or high potential (hipot) test , insulation resistance test and leakage current test. Our complete line of AC, DC and 500VA Hipot testers allows you to meet and exceed electrical safety testing specifications in the US and around the globe.

We can help you eliminate uncertainty with your test procedure , improve safety, and increase throughput. This method requires connection of utility neutral or another grounding system so that the signal goes out to the other system and returns to the test point through the earth. Usually, a common distribution line grounded system can . AC power mains will allow, our ground bond testers can. Our model M2 M3 M3 and M.
