Answer Posted / sunil guru
EVEN NOW DC MOTORS ARE PROFFERED BECAUSE.....
1.HIGH STARTING TORQUE.
2.EASY CONTROL OF FIELD EXCITATION SO SPEED CAN BE
CONTROLLED
3.HIGH SPEED VARIATION IS POSSIBLE
4.BETTER STARTING AND BRAKING CHARACTERISTICS
used in lifts,hoists,cranes,traction systems........

what is the voltage between earth & neutral in 3 phase electrical connection.
In a 3 phase 4-wire system. For a 3.5 core cable if all loads are single phase and balanced, what will be neutral current? will it be sum of all phase currents? Or it will be zero? And if loads are unbalanced what will be neutral current?
how to select fuse rating for a 3-phase motor ???
Incoming line 11kv And transformer capacity is 2500kva. Consumption load is 1300A. Then fuse capacity is 11kv line.
How can I calculate per unit (KWH) fuel (Gas/ Diesel both) consumption 1MW unit?
What is the method of estamating of cable, CB,MCB ?
WHAT R THE SAFETIES IN A HIGH TENSION PANEL N LOW TENSION PANEL. ALSO WAT SAFETIES R THERE IN A 200 KVA TRANSFORMER?
A 100 kVA , 400 v/250 kv testing transformer has 8% leakage reactance and resistance on 100 KVA base . A cable has to be tested at 500 kv using the above transformer as a resonant transformer at 50 hz . if the charging current of the cable at 500 kv is 0.4 A find the series inductance required . Assume 2% resistance for the inductor to be used and the connecting leads . Neglect dielectric loss of hte cable . what will be the input voltage to the transformer ?
