generator?
Answer Posted / zahid ali
On transformer
1- Insulation Resistance
2- Di-electric loss Factor or Tan delta or Power Factor test
3- Polarity & Vector Group Test
4- Transformer Turn Ratio Test
5- Sweep Frequency Response Analysis
6- Temperature Rise Test
7- AC leakage Test
8- Dissolve Gas Analysis Test On Oil
9- Short Circuit & Open Circuit Test To determine losses
On Generator
1- Insulation Resistance & Polarization Index
2- Hi Pot
3- Short Circuit Test
4- Power Factor Tip up test
5- Partial Discharges Test
6- El Cid Test (electromagnetic core imperfection detection)
7- Retaining Ring Test (Ultrasonic)
8- Recurrent Surge Oscillation Test on Rotor (RSO)
9- Low Resistance Test
10- AC Leakage Test
