When checking the voltage during IVV testing, what is the expected voltage?

During IVV (Inspection, Verification, and Validation) testing, the expected voltage is 0 Volts. This is because one of the primary objectives of IVV testing is to verify that the system is not live and that there is no voltage present in the system being tested. This ensures the safety of personnel and equipment before performing any maintenance, repairs, or troubleshooting activities. By confirming that the voltage is 0 Volts, technicians can proceed without the risk of electrical shock or other hazards associated with electrical systems that are energized. This procedure is an essential safety measure in any electrical work to protect both the technician and the equipment.
