How do you perform a voltage drop test
WebDec 20, 2024 · Voltage drop testing allows the technician to monitor voltage loss in a circuit. Voltage drop should be checked with the circuit loaded and a fully-charged battery. Show … WebBreakdown at XX kV - A voltage breakdown took place at the indicated test voltage, meaning there was a flashover at the fault. No flashover - The cable has withstood the applied DC test voltage. In this case, no current will be indicated. If required, repeat the test with a higher voltage (do not exceed the maximum permissible voltage).
