  • Transformer testing | Commissioning, routine, diagnostic

    Electrical Test Recommendations For TransformersRoutine ScreeningDiagnosticA primary part of commissioning a transformer involves testing it after its installation in the field. This amounts to a rigorous examination of the transformer intended to: 1) uncover problem(s), if any, with the transformer’s components, as a transformer is exposed to great stresses on its journey to site and is vulnerable to moisture ingress during installation and other unplanned maladies, 2) validate that the transformer tests the same as it did when last tested at the manufacturer’s facility, 3) establish a baseline with which to compare results of future tests. For many tests, this will be almost essential to diagnose problems effectively in the future. The electrical tests recommended for commissioning a transformer include: 1. Transformer turns ratio 2. Bushing CT ratio 3. Tan delta/ Power factor/ dissipation factor (50/60 Hz) 4. NB DFR (narrow band dielectric frequency response), 1 – 500 HZ 5. Dielectric frequency response (DFR) 6.
