An induction relay works only with alternating current. It consists of an electromagnetic system which operates on a moving conductor, generally in the form of a disc or cup, and functions through the interaction of electromagnetic fluxes with the parasitic Fault currents which are induced in the rotor by these fluxes. These two fluxes, which are mutually displaced both in angle and in position, produce a torque that can be expressed by
T= Κ1.Φ1.Φ2 .sin θ,
Where Φ1 and Φ2 are the interacting fluxes and θ is the phase angle between Φ1 and Φ2. It should be noted that the torque is a maximum when the fluxes are out of phase by 90º, and zero when they are in phase.

What is an Induction Relay with shaded pole?
It is a device used to protect Electric Network and loads
What is squirrel cage induction generator?
Squirrel cage type is a type of Induction motor. It tells that the rotor is "squirrel cage" type. Another type of induction motor is with "slip ring" type of rotor. Squirrel cage type is most widely used Induction motor.
What is meant by IDMTL type relay?
Inverse definite minimum time lag relay
Which type of motor is used in heat convector?
The fan in a convector is usually a single-phase induction motor.
Which type of ac motors are used in air cooler?
generally induction motor of single phase is used in air cooler.

What type of induction motor used in ceilinf fan?
Could be a single phase induction motor of 20-40 watts.
What type of motor is used in ceiling fan?
single-phase induction motor is used in ceiling fan.
A clamp-type measuring instrument operates on the principle of?

What type of motor used in exhaust fan?
Induction motor
What are the health hazzards of food cooked on induction cooker?
There are none- The induction heats the pan (PS- HAS TO BA A CERTAIN TYPE), not the food directly. There is as much harm in induction as there is in traditional hot-plate.
Working principle of induction type instrument?
it works on the principle of induction i.e. on the production of eddy currents in the moving system by the alternating fluxes
What type of range uses electromagnetic energy to heat food?
Your mum has got a big tumour and your grandads a cancer patient
How relay is used to control induction motor?
If you want to control induction motor using a control relay give neutral directly to the one point of coil of relay & one point of coil of contactor then give control supply through push button to second point of coil of relay. use one NO point of relay and give supply to coil of contactor. and also use one NO of contactor for holding the contactor & take OFF (NC) in the starting to stop motor after complition of work. It is jut like an Direct On-line starter.
Which type of relay is used in short transmission line?
Ohm relay.......
