5 10642what happens when back feeding supply accidently collapses with normal supply ??? How?? [that is sometimes in a substation 11kv feeder if their ws long time permit work, back feeding supply will provide from nearest substation... if accidently after the permit work,they charged the feeder without removing back feeding wat will happen...?]

Why negative feedback is preferred in the control system?
Hello everyone, somebody knows what is a "surplice power" ? The hole phrase is: "This rating is appropriate for a generator set paralleled with an infinite bus e.g. a national electrical supply network or grid where the generator set is run at 100% load, 24 hours a day, 365 days a year and any surplice power is exported into the grid" Thanks in advance.
In india, according to trade theory above 5 HP motor reqired star delta starter. But we R connect 11 KV motor with 14MW in Direct to line ( With VCB starter combination) Can U Guess, How it is possible ?????

hi friends this is a newcomer in your community of enthusiastic peoples. i am preparing for SSC (CPWD JUNIOE ENGG EXAM FOR ELECTRICAL) pls guide me on the same how to crack it? PLS LET ME KNOW IS ANYONE THERE WHO PASED IT? CAN I GET THE QUESTION PAPERS OF PREVIOUS EXAMINATIONS?
What is the distance between each insulator in 33kv transformer and how can it calculate
A 500 V shunt motor runs at its normal speed of 250rpm when the armature current is 200A. The resistance of the armature is 0.12 Ω. Calculate the speed when a resistance is inserted in the field reducing the shunt field to 80% of normal value and the armature current is 100A.
we are having 15kw and 3kw motor both can run in same time , instead of using copper we are using ug aluminium cable , 35 sq.mm is suitable for its current carrying capacity..?
