If the (Motor control center)Panel work on field the relay used in panel in the case this will be damage and no indication provide on panel.fault occur in panel and MCB will not trip. how happen the relay damage in panel and what effect of panel.
1 4151suppose MCC (Motor control center)panel work on field the relay on this damage or not work and earth fault occurs in this and no indication in relay panel given below. than MCB trip or not and what effect the panel how find relay will damage or not work.
2 4883Our Company's Contract Demand is 110 kVA. We use 12 Capacitors each of 12.5 kVAr Capacity to maintain Power Factor of 0.99. So, what steps should we take so that our Contract demand does not exceed 110 kVA?
1 3970There is 15 KVA UPS using for single phase load.And 30 batteries of 12 V, 100 Ah are connected in series. Load is taking 15 A current.What will be the back up power for this UPS on same load?
1 3572What will happen if the field of synchronous generator is removed when it is in operation with no load?

What is the need of earthing transformer for delta side of a transformer. (Think of a line section between a star/delta transformer at a grid substation and delta/star transformer at a village. An earthing transformer is there at the delta side of the star/delta transformer at grid substation). As there are no ground reference there will not be fault current if a one phase is grounded. Further L-L phase will be sensed by the primary side of star/delta transformer as a L-G fault. So why an earthing transformer is required at delta side
