Say a transformer to be charged. Its LV side and HV side breakers are open. Which breaker to be closed first? HV side or LV side??? And also if the same transformer to be cut out then what's the sequence? plz help me out with proper explanation..
 
Once the transformer charged, it should be discharged before closing the breaker either LV side or HV side.

To discharge the Transformer, take cable of >10sqmm connect one end of the cable to one phase and other end of cable to the ground (earth pit).
Do the same with all the phases on both LV & HV side. care to taken while doing, insulate your self before attempting.

once it is discharged, it is ready to operate as usual.
 
It depends where u r connecting the load. if u are connecting the load in LV side, then u need to close the breaker for HV side first and vice versa.
