Hi friends,REL team had visited our college on26th dec ,coming to selection process ,it
consists of 3 rounds.
1. Written test
2. GD(not an elimination round)
3. Interview (technical)
WRITTEN TEST (electrical)
It consists of 30 objective questions, these r problematic as well as theory questions. i
 remembered few questions.
1.      In a series RLC circuit Fo is resonace frequency, if LC r doubled wat is new
resonace frequency?
2.      R=5 ohm, V= 5v, f=200 hz, and given conditions r VL=VC= 2VR , find L=?
3.      Comparision between maxwlls and hey bridge.
4.      VPQ=?
5.      Find R in a balanced bridge network.?
6.      Choose right statement among following….
                 ANS: CT secondary should not open.
7.      In a Transfer at no –load friction and windage losses r called as
………..(ans : Iron losses)
8.      Maximum power transfer through line ..V1= 110 kv, V2= 100kv, X=22 ohm,….(
ANS: 500 mw)
9.      Shunt reactor effect on Trans. Line
10. Series capacitor effect on Trans. Line
11. Velocity in distilled water(e= 81)…magnetic field intensity find electrical field
intensity(I did not remember)
12. Question on pointing vector
13. If a dc machine (p=6;z=some value ;r=some value having lap winding then re
winded machine winding as a wave winding find armature resistence?
14. In a Dc series motor having 2 pice of field winding in series if the field winding is
re- wounded as two parallel paths then speed of motor(at constant torque)
15. For above rated speed the type of speed controls method (in case of DC motor)?
16. Statements regarding transformer (1.constent flux.2..3..4..)
17. Question on regulation of alternator at zero leading PF(ans : -50)
18. Question on power transmission in T.line . T.line having 2 generators at either
ends A,B.
To reduce the power angle …….
ANS: decrease power B and increase power A.
19.regarding relay parameters, settings.(problem)
20. in a synchronous motor if load is increasing then armature current is decreasing then
initially machine is operating at what PF?( I AM NOT SURE …..
21.IN slip ring induction motor if the supply is given to rotor and stator is SC’ted then
the speed of motor W.R rotating magnetic field? what condition syn machine absorbs reactive power ?
23. Question on parallel operation of alternators load sharing?


Hello freinds, The Reliance Energy Limited came to our college. the process includes
1. written technical -total no of questions is 30 , time 40 minutes no negative
marking(elimination round)
2. GD(non elimination round)
3. PI

WRITTEN TECHNICAL (Electronics & Telecommunication)
The questions were mainly from Instrumentation and control system.they require
instrumentation engineers.
2 numerical quetions of digital communication 1 from sampling frequency.
1 from optical communication very simple que.
6-7questions from control theory mainly used in power plant related to cascaded
controller, PID, second order transfer function, steady error rate in thermometre.
Q The op-amp in non linear mode is used as a) integrator b) schimmt trigger c)active
filters d) instrumentation amplifier.
1 quest on IR spectroscopy, stroboscope, pirani guage, 2 questions related to flow
measurement, vacuum, Bellow's expansion.
1 numerical on LVDT
1 optical lens magnification numerical
1 question from current transformer(find error rate)
1 question from Geiger tube (quantum efficiency in Angstrom)
Q friction related question of 12th class
Q.The decimal no. -15 can be written in 8-bit signed 2's complement as?
Q The no. of flip- flops used in MOD-10 counter is
Q The deflection sensitivity of CRT is directly/inversely proportional to
QThe common collector configurations characteristics is a) high i/p & low o/p
impedance....................................... package 4.5 lakh per annum, and no service bond

REL recruited in 3 rounds:

1. Technical test according to ur branch ( 30 questions)(cutt off was 33%) -
mechanical, electrical , electronics , civil or environmental ( ITS AN
2. Group discussion on topics related to energy , pollution , environment etc.(like
nuclear deal , conservation of energy etc.) ( ITS not an ELIMINATION ROUND
3. Interviev( HR + Technical)...basic Q from ur branch of engg. mainly from 3rd
and 4th semesters.

scores are given for each round and the final total is done to get total score and
the person is selectes on the final total score.

As it is well known that india`s energy needs are going to double in the next 6 to
10 years the of power sector is on boom at present and therefore
Energy/power companies are recruiting ppl in large numbers now so u have high
chance of getting thru.
REL is paying a handsome pay to its recruits.
