Question   What is the winding resistsnce need to be in a 1000kva, 11kv/415v transformer, between ht winding to lt winding, ht winding to earth, lt winding to earth.? Rank Answer Posted By
Interview Question Submitted By :: Niharr.pradhan
I also faced this Question!!   © ALL Interview .com
You mean insulation resistance ?As a rough guide,the megger
value should be at least 2 M ohm per KV rating at 60'C for
11 KV and above.The megger value doubles itself for every
10'C fall in temp.

Question   What is the formula to find out the kvar required to improve the powerfactor from .85 to .99 at 1500kw, 415v. Rank Answer Posted By
Interview Question Submitted By :: Niharr.pradhan
I also faced this Question!!   © ALL Interview .com
first calculate the kva at .99 and 1500kw
(cosp=kw/kva),than put the value of kva in this formula kva=
(kw)2+(kvar)2)^1/2 to caculate kvar at .99 pwr factor

0 Waqi

The KVAR required is:

KVAR=KW(tan@1-tan@2) (where @1=cos-1(p.f1)& @2=cos-1(p.f2)

Therefore,

KVAR=KW {tan[cos-1(p.f1)]-tan[cos-1(p.f2)]}

=KW {tan[cos-1(0.85)]-tan[cos-1(0.99)]}

=KW {tan[31.79]-tan[8.11]}

=KW {0.48}

=1500 {0.48}

=720

Therefore 720 KVAR is required to improve powerfactor from
0.85 to 0.99 for 1500KW load.

NOTE:-
Excuse me if the answer is wrong.

Dear Waqi

I am not understand your answer for the above mentioned question. Will you please solve and give us the answer for required KVAR to improve power factor from 0.85 to 0.99 for 1500KW load.

0 Habeebm
[Trident Hotel]

KVAR=KVA*SIN(PHI)
KW=KVA*COS(PHI)

HENCE....KVAR/KW=TAN(PHI)

KVAR=KW*TAN(PHI)

NOW, FOR P.F.(1)=COS(PHI(1))=.85 THEN TAN(PHI(1))=.6197
FOR P.F.(2)=COS(PHI(2))=.99 THEN TAN(PHI(2))=.1425

KW=1500 KW IS COMMON FOR BOTH CASE 1 & 2

REQUIRED....
KVAR=KW*[TAN{PHI(1)}-TAN{PHI(2)}]

HENCE KVAR=1500*(0.6197-0.1425)=715.8

YOU NEED TO ARRANGE CAPACITOR BANK OF 715.8 KVAR.

ACCEDENT WILL NOT OCCUR.

it is because cracks in insulation can be better identified
in grey colour .this reason also holds gud for  other
insulators also.

5 Shelja Singh

because cracks can be easily detected on grey color.

0 Dinesh Joshi

The Grey color was standardized due to economic reasons cr.1945 after a surplus of Battleship Grey paint during WWII.

I believe the color is blue gey and it was deigned by a
first lady. It makes the equiptment seem to disapear in
most skys. I think it was Nancy Regan not sure.

Question   what is the role of proportional in process control? Rank Answer Posted By
Interview Question Submitted By :: Waris
I also faced this Question!!   © ALL Interview .com
Normally In PID Controller Proportional gain and integral
time is important parameters
in Process control we are using several parameters so we
maintain a pertucular level of the system proportional is
used.

0 Rajesh

proportional control is used to linear
increase(relationship) with the controlled variable and to
the final control element

0 Dinesh
[SML]

To maintain one-to-one correspondence between error signal
and manipulated signal.

0 Sattar
[SML]

proportional controller changes the controller output with
respest to error
but it produces linear offset
p=kP eP

0 Rajesh Kumar
[SML]

It is the amount the measurement must change to move the
valve (final control element) fully open or fully closed in
a control system.

0 Rt Langley
[SML]

In controller must be used proportaional (P). according to
change in input it 'll change the output. means output is
proportional to the input. if controller is direct action
it 'll be directly proportional and if controller is
reverse action then it 'll be inverslly proportional. Keep
in your mind controller input is always an error signal.
