Which of the following conditions have to ensured for a short-circuit ...
Conditions for a Short-Circuit Test:
1. h.v. winding is short-circuited:
- In a short-circuit test, the high-voltage (h.v.) winding of the transformer is short-circuited. This allows for the determination of various parameters such as copper losses, impedance, and temperature rise.
2. Calculation of voltage regulation:
- The short-circuit test helps in calculating the voltage regulation of the transformer. This is crucial for ensuring that the transformer operates efficiently and within the desired voltage limits.
3. Not performed at rated voltage:
- Unlike the open-circuit test which is performed at rated voltage, the short-circuit test is not performed at rated voltage. Instead, it is typically conducted at a reduced voltage to prevent damage to the transformer.
Therefore, the correct conditions that need to be ensured for a short-circuit test are:
- h.v. winding is short-circuited
- It helps in calculation of voltage regulation
