What are some of the Tests performed on transformers?
Normal, routine production tests include:
- core loss;
- load loss – winding or copper loss;
- Impedance;
- hi-pot – high voltage between windings and ground;
- induced – double induced two times voltage.
Optional special tests include:
- heat run – temperature testing;
- Noise tests – sound level measurement;
- impulse tests – BIL tests:
- partial discharge
