what are the advantages and disadvantages of speed control of 3 phase induction motor by varying frequency explain with drawing
1 2754draw the restricted earth fault protection circuit install on power transformer and identify its parameters and draw C/C curve of it
1 2800- two pumps must work with them at the same time but if the first pump start the second pump must delayed for some time to start also , with motor rated power = 90 KW and rated voltage = 380 V and rated power factor = 0.85 lag please draw the power and control circuit for it and determine all circuit components parameters that you use it

what is mean by restructuring power system?
Can you used moeller lzm1 mccb in a dc system with 125vdc and 20ka short circuit current , beside is it have 24 or 48 volt shunt ? Beside how long current can through from An MCB shunt contacts? (like Z7-AS 24 V)?
Is it possible to measure correct value of earth resistance & cable insulation ristance with out disconncting earth lead & both sides of cable ends? If not, any other method to measure ER & CIR with out disconneting from the system.
pls,send the previous year written test questions.
What are the different methodes for calculating the short circuit Current?
hi can anyone pls tell me the eee interview core questions asked in l&t
