L&T ECC PAPER - 26 JUL 2007 - PUDUCHERRY
I am Praveen Kumar, from pondicherry engg college, Puducherry,
On 26-07-07, L&T(ECC) came to our college for campus recruiting, besides our college Annamalai university students were also participated in recruitment,
The selection process is different for graduates and post graduates,
I am doing M.Tech (electrical), for one hour they conducted test for 60 marks, 30 one mark, 15 two marks, no negative marks.
The test was completely based on respective subjects only; they are allowing mechanical, civil, environmental engg students along electrical.
The subjects they covered are power systems, power electronics, electrical machines,
Electrical measurements, simple logical circuits,
I remembered only few questions
* Convert 26 into binary form
* In which gate o/p is 1 when all i/p are 1
* What is the 2’s complement of -17
* What is moving coil ammeter reading, if supply is (10+15 sin 314 wt),
* If voltmeter reads 100V, if we want to measure 150 what we have to do
* Y-delta starter is used for
* In a balanced Y connection if VAN=400at 60, what is VBN
* for unity TMS 10 sec, what about 0.5 TMS
* 400V,15 kW,4%slip,50 Hz, 4 pole what is the torque,
* what r the factors influencing change in torque &speed
* buccholtz relay is used for
* lightening arrester is used for
* what is the power dissipated in i=10+5 sin 314wt for 2ohm resistor
* what should be the impedance value for 3-4j,for max power transfer
* if current required for triggering thyristor at -30 degrees(temp) is 80 mA, what is the current required at 60 degrees.
* Question regarding thevenins resistance
* Question regarding periodic Fourier series
* Question regarding reactive power compensation
* Question regarding positive sequence currents
* 400v, 50ohm resistor, inductive reactance 100ohm, circuit to be resonance, find the voltage across capacitor
* what is the ideal power loss for 1.1mH & 11.86 nF, length is negligible
* sync motor is used for
* regarding p.u. values
* regarding voltage bus parameters
* charging of capacitor
* reactive power compensation
* Y-bus, Z-bus 2 x 2 matrix
* Poles location
* I controller is used for
Finally the paper is simple, prepare some basics.
