As per IS 2026 the following Routine tests are carrying out in transformers at testing stage.
1. Measurement of Winding resistance
2. Voltage Ratio/ Ratio Test
3. Measurement of Impedance voltage/ Short Circuit impedance
4. Measurement of NO-Load loss and current
5. Dielectric tests (Induced Over Voltage and Separate Source Voltage)
6. Magnetic Balance and Current
7. Load Loss
8. Insulation Resistance
9. Vector Group
10. Oil BDV
11. Capacitance and Tan delta
Tests at site will be discussed in next post.
