Can anyone send details regarding motor protection relays ?
their manuals please ?
how the ac voltage are selected like 220v,415v,750v,1000v& 1.KV,6.6KV,11KV,33KV,66KV,132KV,220KV & why these are selected like these orders
WHY SEPARATELY EXCITED MACHINE NEEDS EXCITATION BY DC SUPPLY WHY NOT BY AC
why dc supply is not applied for step up or down in transformer
what will happen if dc supply is given to ac motor?
when it is possible kvrah lead & fundamental kwh be equal in electonic trivector meters (3 ph)
in Megger what type of voltage(AC or DC) are produce.how they work.
What is meant by operating sequence of VCB : 0–0.3sec.–CO– 3min.-CO
what is meant by vector group of a transformer? How can it be derived?
why we use CVT (capacitive voltage transformer)in switch yard?
FOR ELECTRICAL TRANSMISSION TOWER WHAT SHOULD BE THE MINIMUM HEIGHT FROM THE GROUND? AND WHAT SHOULD BE THE DISTANCE BETWEEN THE TWO CONDUCTOR?
how the global warming take place?
IN WHICH MODE THE TRANSFORMER WILL GET A MAXIMUM OUT PUT VOLTAGE. ASKED FOR POWER GRID EXAMINATION STAT-STAR,STAR-DELTA,DELTA-STAR,DELTA-DELTA
