Which method is NOT used to test for a de-energized line?

In the context of testing for a de-energized line, the use of an ohm meter is not a standard method by which linemen confirm that a line is safe to work on. An ohm meter measures resistance in a circuit, which can indicate whether a connection is good or not, but it does not directly confirm that a line is de-energized.

To ensure safety, linemen typically employ methods that check for the presence of voltage or high residual current. High voltage voltmeters can measure the voltage present in a line effectively while identifying whether the line is energized or not. Insulation testers assess the integrity of the insulation which can also indicate if it’s safe to work on and whether current is present. Fuzzing is a technique where linemen check for voltage by using a device that detects electromagnetic fields around conductors, thereby establishing that the lines are not under potential voltage.

In summary, while an ohm meter provides useful information about resistance within a circuit, it does not serve the purpose of verifying that a line is de-energized and can therefore lead to unsafe working conditions if relied upon for that intent.
