You can test VT by two methods:
A. HV test:
1. Short all the primary terminals together including nuetral (remove the neutral from the ground).
2.Short all the secondary terminals and ground.
3. As per IEC, for 24kV rated equipment, power frequency withstand voltage is 50kV.
4. Apply 75% of 50kV...
