Dnyanesh replied to the topic Why synchronous generators are used for generation of electricity? in the forum Common electrical queries 2 months, 3 weeks ago
Synchronous Generators or Alternators helps in maintaining same synchronous speed of generators within system.
As stated by AP above,
f= Frequency of the power
Ns= Synchronous speed of the individual generator
P=No. poles in the generator
No. of poles in the generators are constant i.e. we use 4 no. of poles in…[Read more]
Dnyanesh replied to the topic short circuit combination for load test of transformer in the forum Common electrical queries 10 months, 2 weeks ago
In the short-circuit test of transformer, LV side of transformer is short circuited while HV side is subjected to rated voltage. The watt-meter , voltmeter and ammeter are connected at HV side which measures copper loses( as core losses in short circuit test is negligible), short circuit voltage, and short circuit current respectively.
