What is a protective conductor test?
The protective conductor test is one of the most important tests in thefield 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 conductor test, the user is at the mercy of the touch voltage because the current is not completely discharged to earth. An intact protective conductor ensures that the touch current is discharged to earth via the user. This significantly minimises the potential danger.
