It may so happen that the single phase test doesn''t show a failure, however. How? Imagine each phase being filtered by an EMC filter which usually contains capacitors from phase to ground. When testing a single phase, the AC current through the capacitor(s) connected to this phase may be low enough to not trigger the high pot tester.

How to Test a Capacitor?
Why do we need to Test a Capacitor? When a capacitor is placed in an active circuit (a circuit with active current flowing), charge starts to build up in the capacitor (on one of its plate) and once the plate of the capacitor can no longer accept any more charge, this means the capacitor is fully charged.. Now, if the circuit demands this charge (like a bypass …

AC HV test value should not surpass 75% of the factory test value. When AC hi-pot tests are used for routine maintenance, the power transformer can be examined at rated voltage for 3 min instead of testing at 65% of factory test voltage. The AC hi-pot test values for voltages up to 69 kV are presented in Table 1. Table 1.
