Types of Electrical Transformer Tests· 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.

How Transformers Age | T&D World displacement of the transformer winding coil also was noted in the other transformers, from different manufacturers, located at the same power plant. As a result of the investigation undertaken when the transformer was decommissioned, the clamping force had decreased by approximately 60% and the winding displacement decreased by 40%.
