What is forward reverse
starter ? What is earth resistance for 1500 KVAR ?
Forward converse starter is utilized
to run the engine in the two sides forward and turn around & 5 Ohm
In a 3-phase motor, the
reading is 2500kwh & 1000kvar. What is PF?
P=25001000/3600=394.45W
Q=1000KVR
S= √694,45^2+1000^2 =1217.50VA
P.F=PS =0.570
In a LT panel R 150A, Y
162A & B 155A. What is total power where V = 400 & PF = 0.98
P.F=0.98 Pr=400*150*.98 =58800w
=58.8kw
Py=400•162•.98 =63.504kw
Pb=400•1555•.98 =60.76kw
P total=58.8+63.50+60.76 =183.064kw.
