Safety mechanisms designed to handle rare events can become unreliable under sustained or intense fault conditions.

HISTORY: High Resistance Grounding is a means of limiting ground fault current in electrical systems. Unrestrained fault current can cause severe equipment damage, product destruction, and personnel ...

The digital voltmeter is the best basic tool for electrical troubleshooting, because it's calibrated and exact. But remember, the digital voltmeter can't detect a high-resistance fault if the circuit ...

In the second part of this series on the highs and lows of resistance measurements, I illustrated the differences between two-wire and four-wire resistance measurements on an actual low ohmic sample ...

If your circuit design has requirements to be tolerant to certain faults and to report their occurrence, you’ll need to test the fault detection and protection features of your design during the test ...
