Guide for Testing Power Transformers - The Balance Small ...· Power Factor Testing . The power factor test determines the power loss of the transformer's insulation system by measuring the power angle between an applied AC voltage and the resultant current.Power factor is defined as the cosine of the phase angle between voltage and current. For ideal insulation, the phase angle is 90 degrees, but in practice, no insulation is ideal.Get Price
