I think that site tests.ie. Pre commissioning Tests of
following.
1. Insulation Resistance Test for breaker and protection
and other cables
2. Check for spirit level
3. Mechanical spring charge test
4. Mechanical ON/OFF test
5. Electrical spring charge test
6. Electrica ON/OFF Both Local and remote Test
7. Contact resistance Test
8. opening and Closing timings tests.
9. Protection trip Test
10. Check for operation of Closing coil at 80% and Trip
coil at 70% rated Control D.C.voltage

Its possible to use 3core 2R of 240 sq.mm cable for 3phases & separely 50sq.mm 3core cable fully for Neutral for connection of PCC to MCC 3ph..4wire system?
how can i get the formula to find out the cable size if i know the load of main fuse protection.
in HT service 3ph 4 wire service Y-phase voltage shows zero . whether it is meter fault? or what be the reason ? if y-ph voltage zero ,can current is recorded? reasons for failure?

As per standard, transformer body earthing and other Equipment earthing (Equipment earthing) did not connect. but in LT side termination we are doing metal glanding in both side Transformer to PCC Panel through armoured cable, now X'mer body earthing and PCC Pane earthing (Equipment earthing) both are connect.is this safe for X'mer or other equipment?
