we have 3*1 MW generator one NGR is common for all it will
be selected during paralle our problem is two generator ca
be paralled but when slecting third one we need to close
NGR selection on third one other wise voltage not matching
In Power Line Communication (PLC) the wave trap is used to
block communication signals from entering neighboring
lines. My question is this: Why do they allow for
different filtering arrangements on these wave traps?
Isn't it always going to be a low pass filter since we want
the power frequency to go through, and the comm signal
i want to know how to determine that a surge arrester
work properly in 11kv system. and how to test a 12kv surge
Difference between low impedance and high impedance

iii) A shunt motor runs at 70 rad/sec from a 460V
supply and takes in an armature current of 100A. Resistors
of 2.52 ohms and 1.64 ohms are connected in series with the
armature and in parallel with the armature respectively.
The field excitation remains direct from the 460V supply
but the generated torque is halved. Determine the new
running speed. Neglect brush voltage drop. The armature
resistance is 0.4 ohms.

IN MY SYSTEM THERE IS ONLY OVER CURRENT EARTH FAULT RELAY
IS AVAILABLE. FOR THE UNBALANCE SENSING IS THERE ANY RELAY
IS AVAILABLE? THE SAME CTs WHICH ARE USED FOR THE OVER
CURRENT EARTH FAULT RELAY CAN USE FOR UNBALANCE ALSO?
