TYPE TEST AND ADVANCED TEST FOR TRANSFORMERS, ELECTRICAL WIRE AND CABLE, LIGHTNING ARRESTERS

They are significant tasks which help the investor assess and control the quality of transformer,electrical wire and cable, lightning arrester... to minimize power loss as well as incidents which may occur during operation.

1 Advanced tests as follow:

- Advanced tests for transformers: No load lossing test (Po), short circuit loss test (Pk) at rated conditions; heat run, noise level, lightning impulse, partial discharge for electrical transformers;
- Quality assessment test of electrical wires and cables;
- Lightning arrester test.

2 Other tests as follow:

- Induced voltage withstand test;
- Power frequency withstand voltage test on power transformers up to 500kV, power cable up to 220kV, GIS up to 750kV (HV AC );
- Partial Discharge measurement (PD);
- Sweep frequency response analysis (SFRA);
- Moisture amount content in hardened solid insulation.
