11Kv Dog conductor 6/0.186 formula Line Losses ? Length 4.85Km amper ..? 52 Pole Max Load 3200Kw
what is protections used for 6.6kv ht motor
what are the different types of transformers in present? which transformer is efficient?
why we r used DC megger insted of AC megger?
Is there any capacitor in 3-phase IM?why,xplain.
WHICH TYPE OF TRANSFORMER USED IN SWITCHYARD IN POWER PLANT?
A 50Hz,4-pole,3-phase,star-connected synchronous motor has a synchronous reactance of 12ohmsper phase and negligible armature resistances.the excitation is such as to give an open-circuit voltage of 13.2kilovolt.the motor is connected to 115kilovolt, 50hertz supplying. what maximum load can be the motor torque,line current and power factor?
What, in the construction of a transformer, controls KVA? For example 600/208/120 V transformer can be 10kVA or 45kVA!!! What do we change in the construction of a Transformer in order to change the rating but not the voltage.
In DC current-excitation to transformer, why it sucks more current? Eventhough there is no power transfer between primary and secondary? R is very low so it should suck less current only na thn y its current increases?
The earth pin of some three pin plugs are seen split. why?
Why starters are using the machines???
