Induced voltage tester
Web14 mrt. 2024 · Low-Voltage Induced Voltage Scenario. 4. It could be backfed. Control power transformers (CPT), indicating lights and “foreign” circuits (those coming from another panel or area) can be the culprit. Applying a static ground to a backfed circuit could cause arcing, which is unsafe. WebAt the cross-bonding link boxes, a nonlinear resistance is used to reduce the induced voltage in the cable sheath during a fault condition to test the insulation of the sheath voltage limit (SVL). Leave the three terminals of SVL connected to earth and the other three terminals are then able to measure each free terminal of the SVL.
