Answer / k.prakashchandra
This relay is actuated by any relay connected to it and it
will trip all the equipments, relays of which are connected
to it.

how we can set the IDMT relay.
1. The DC generaror,s induced output emf is connected with a DC motor(as load). when increasing the load of the motor by using brake drum or any way. what are the parameters will changes in both motor and generator(voltage, current, resistance, frequency, speed, torque, power, flux etc...) 2. Similarly for AC generator and AC motor 3. similarly if using DC batteries instead of DC generator, What happens?
what is load balancing. what maximum load diffence is allowed between phases.
which motor is used in high mast ( street light) & give the hight of tower .

In Dyn11 power transformer if any one of the 3 phases connected to earth in star connected side then please explain effect of the current flow in delta connected side of transformer.(In this case if one phase is shorted to ground in star connected side then we observe the current flow in two phases only not three phases in delta connected primary side. Please explain why it is so?)
why onlyseries motors are used as universal motors? why not shunt?
