PREPARATION OF TRANSFORMER SPECIFICATIONS

When an old single-phase transformer fails, it is often replaced with a new single-phase transformer. For a functionally identical new transformer, losses, weight and dimensions are often much lower than those of the old transformer. This is due to improvements in materials, accurate design analysis with advanced mathematics, computers and better

Transformer Installation, Assembly & Testing

process and test the transformer are of fundamental importance to the long life of the transformer. •The installation and testing of the transformer verifies its condition at the time it is ready for service as well as forming the baseline or signature tests for all future maintenance and later condition assessment or analysis.

Partial Discharges in Electrical Insulation

PD Testing of Power Cables •For oil-paper transmission class, primarily use on - line PD •All XLPE and EPR cables: all factory PD tested •In-situ off-line PD testing: use 50/60 Hz or VLF (0.1 Hz) to energize the power cable capacitance •On-line PD testing of cables sometimes also performed – but high risk of false indications due to
