how to understand the controling circuits example star- delta-starter controling daigram please let me know
i am electrical and elctronics engg passed out in 2009 want to attend for reliance placements.plz send me apttitude ,technical and hr question answers to my mail plz. my mail firstname.lastname@example.org
Is C.T will sense the current in both direction. As i know the C.T will sense the current in only one direction.2 3906
Why the cost of CT increases with the decreasing of its CT Ratio (Technical Reason)?2 3572
How the size of transformer decreases if we increases the frequency?2 3637
how to synchronize 3 phase slip ring induction motors of different ratings.
can we use existing delta star with neutral grounded,step down(6.6kV/415V), 3 phase power transformer bi-directionally.
want happens when a dc is given to a commutator2 2896
A three phase transformer 460v primary 220v secondary (three phase four wire system.) Why did we get 460 volts across the neutral on the secondary side?3 4350
I have 12MW gas engine based power plant its running parallel with grid. my problem is When cpp run in island mode(without geb) that time geb transformer power factor is 0.2 lagging. When cpp run with parallel that time power factor is 0.94 lagging So how can i maintain power factor ofgeb transformer in island mode 0.9 lagging?
what is mean by NPS (Negative phase sequence)fault? what is the difference between EFR & OCR faults?
What is the function of RCBO? What are the different sensitivity ratings & each application?
what is mppt (maximum power point tracking ) and how they used in solar power generation ??? what are the main components used in mppt?????
Do u know any one? how to find out in motor rated amps? formula?
What is meant by full pitched winding?
Discribe type of fault in DOL and stardelta startor.
Which type of DG need Netral Earthing?
what will be the maximum winding temperature of 6.6kv HT motor 450kw, Full load current 49A. 50Hz Frequency.
1. The DC generaror,s induced output emf is connected with a DC motor(as load). when increasing the load of the motor by using brake drum or any way. what are the parameters will changes in both motor and generator(voltage, current, resistance, frequency, speed, torque, power, flux etc...) 2. Similarly for AC generator and AC motor 3. similarly if using DC batteries instead of DC generator, What happens?
Hi,iam a diploma in electrical engineering.rtd from indian air force in apr 2007.prsently working in reliance next link as a network maintenance engineer since 2007,can i get a job in motherson sumi.
