Hai, 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 2s 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 voltage 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
