Where the excitation is given either stator or rotor in
actually in power plants?
Answer Posted / ankit
in alternators, we recieve power from
stator side. Now rotor contains
electromagnet to generate poles...so that
rotating magnating field generated by
rotor cuts stator winding.. Hence emf is
generated on stator winding..
Now elecromagnet needs supply to
become magnet.. So excitation is given to
rotor.

Why Transformer Neutral having one earth pit ( more earth electrode resistance) whereas body have many earth pit ( less earth electrode resistance)?
A 100KVA SINGLE PHASE TRANSFORMER 10000/200V,50HZ REQUIRES 300V AT HV SIDE TO CIRCULATE FULL LOAD CURRENT WITH LV SHORT CIRCUITED.THE INTAKE IS 1000W.THE % OF REGULATION ON FULL LOAD AT 0.8 PF LAGGING WILL BE HOW MUCH AND THE SECONDARY TERMINAL VOLTAGE ON 0.8 PF LEADING WILL BE

ii) A shunt motor supplied at 230V, runs at 900 rpm when the current is 30A. The resistance of the armature is 0.4 ohms. Calculate the resistance required in series with the armature to reduce the speed to 600 rpm, assuming that the armature current is then 20A. [12]

I am having a 42KW 3 phase electrical heating furnace, heating element is 80/20 nichrome material, my connections is made in such a way that 2 star connection compromising 2 coils per phase so totally 12 coils, shall if i use it unbalanced star condition (instead of 2 group of 3 phase or 1 group of 3 phase, connecting 4 phases of 5 phases) what will be the consequences and is it acceptable?
