Re: NPTI PGDC Electrical Engineering Exam Paper

As you are looking to get Exam Question Paper of NPTI PGDC Electrical Engineering, so here I am giving following question paper:

NPTI PGDC Electrical Engineering Sample Paper
The armature resistance of a permanent magnet dc motor is 0.8 W. At no load,
the motor draws 1.5 A from a supply voltage of 25 V and runs at 1500 rpm.
The efficiency of the motor while it is operating on load at 1500 rpm drawing
a current of 3.5 A from the same source will be
Options A)48.0% B)57.1%
C) 59.2 % D)88.8%

A single-phase half-controlled rectifier is driving a separately excited dc
motor. The dc motor has a back emf constant of 0.5 V/rpm. The armature
current is 5 A without any ripple.The armature resistance is 2. The converter
is working from a 280 V, single phase ac source with a firing angle of 80°.
Under this operating condition, the speed of the motor will be
A)339 rpm B)359 rpm
C)366 rpm D)386 rpm

The 8085 assembly language instruction that stores the content of H and L
registers into the memory locations 2050Hand 2051H, respectively, is
A)SPHL 2050H
B)SPHL2051H
C)SHLD 2050H
D)STAX 2050H

A 50 Hz, 4-pole, 500 MVA, 22 kV turbo-generator is delivering rated
megavolt-amperes at 0.8 power factor. Suddenly a fault occurs reducing is
electric power output by 40%. Neglect losses and assume constant power input
to the shaft. The accelerating torque in the generator in MNm at the time of the
fault will be
A)1.528 B)1.018
C)0.848 D)0.509

A 50 kW dc shunt motor is loaded to draw rated armature current at any given
speed. When driven
(i) at half the rated speed by armature voltage control and
(ii) at 1.5 times the rated speed by field control, the respective output powers
delivered by the motor are approximately.
A)25kW in (i) and 75kW in (ii)
B)25kW in (i) and 50kW in (ii)
C)50kW in (i) and 75kW in (ii)
D)50kW in (i) and 50kW in (ii)

A hydraulic turbine having rated speed of 250 rpm is connected to a
synchronous generator. In order to produce power at 50 Hz, the number of
poles required in the generator are
A)6
B)12
C)16
D)24
