Ground Bond Tester

The protective conductor test is usually also called ground bond test. The protective conductor measurement, test or ground bond test is a test procedure to ensure the electrical safety of electrical appliances and electronic components. Here, the correct earthing and the protective conductor resistance of the devices are checked and it is ensured that no life-threatening current is discharged via the user if electrically conductive surfaces are touched in the event of a fault.

What is a protective conductor test?

The protective conductor test is one of the most important tests in the field of electrical safety, along with the HV test and the leakage current test.
Protection Class I appliances are tested to see if the protective earthing is intact. To pass the test, the protective earth resistance must be below the limit value of the prescribed standards. Protection Class I electrical appliances have a very high hazard level because they have a metal and therefore conductive housing. The protective conductor test is an immensely important safety test, as it prevents life-threatening electrical accidents. Therefore, it is absolutely necessary for the safe handling of electrical appliances.
LXinstruments attaches great importance to electrical safety, because we are true specialists in this field. We have developed our own safety hoods that can test voltages up to 10 kV. All devices available from us are, of course, CE compliant and meet the current DIN specifications of VDE or other institutes.

Why do you need a protective earth conductor?

With years of use, the insulation of devices can gradually deteriorate. Wear and tear or material fatigue increases the risk of the enclosure becoming increasingly live. Without a protective earth conductor, the user is exposed to the contact voltage without protection, as the current is not discharged to earth. An intact protective earth conductor tester ensures that the touch current does not flow via the user but directly to earth. This significantly minimises the potential danger of the electrical equipment.
