... it. Subsequently, the electrical testing of the transformer follows. Electrical Transformer Repeat Testing • High-current winding test with a DC micro-ohmmeter for transformers to detect creeping faults. • Insulation measurement of the transformer to determine the dielectric absorption ratio and the polarization index to assess moisture in the solid insulation of the transformer core. We offer you the service to visually, electrically, and thermographically inspect your resin transformer at regular intervals.
