The effect of electric shock on the human body depends on

Reactance relay is used to protect against

The purpose of embedding the damper winding in the pole face of a synchronous motor is to

under steay state:
P= (E V sinδ)/ X
change in load on motor, δ adjust to new value
rotor oscillate about its final equilibrium load angle called hunting.
cause:
sudden change in load
fault in supply system
sudden change in field current
remedies:
using flywheel
using damper bar

If the fault current is 2000 A, the relay plug setting is 50% and the CT ratio is 400/5, the plug setting multiple will be

Which motor is used to start heavy loads?

Torque in d.c motor = k* φ * Ia
In series motor φ α Ia
Tα I²
starting torque of dc series motor is high

The positive and negative sequence impedance of a transmission line are
