• Measure the insulation resistance of transformer secondary windings and CT leads with a 500 V megAohmmeter.• Measure the transformer primary insulation with applicable potential test apparatus.• Repeat the preceding test to check all three phases.• Verify the connection of the secondary VT leads by applying a low voltage to the leads and checking for this voltage at applicable devices.• Check for a VT secondary load with secondary voltage and current measurements. Make sure that the load is less than the rating of the VT.
