What is ment by restraining coil?
straining coils are winding that we uses to prevent the fault operation of relay
Where is coil relay on 1986 ford eco van?
There is no such thing as a coil relay.
What is a relay coil?
Most relays have an internal electromagnetic coil that is energized when the relay is activated.
What is a control relay coil?
Most relays have an internal electromagnetic coil that is energized when the relay is activated.
Is a relay considered a load?
The relay's coil(s) would be a load, but the main function of a relay is to act as a switch to control power to a larger load.
A wide air space between a workpiece and the forming coil used in the magneforming operation would have the?
make easy to loading and unloading operation, that's why you need the gap between the coil and the workpiece
What could cause a relay coil resistance to be lower than specification?
A short within the relay coil itself.
What is operation of an antihunting relay in circuit breaker?
This is also called anti pumping relay. for understanding you have to understand the working of breaker. positive extends to "Low Pressure Lockout" & "Low Pressure Alarm". after maintain the pressure in breaker these NO becomes NC and when breaker closes the auxiliary of breaker get closed and simultaneously extend the positive to the antipumping relay coil by auxiliary contact. by this coil get energised and holding contact get connected and the one of the contact of antipumping coil (NC) become NO which disconnect the command supply of main breaker. by this till when the antipumping relay get energised no further command (+ve) extends to breaker closing coil. This is Antipumping/ Antihunting Relay.
How would a faulty photocell be detected?
By covering the photo cell and if the relay coil doesn't work.
When using an arduino controlling a relay- why are resistors used with the transistor to activate the relay coil?
Because without the resistor, there would be a short from the base to ground, and sometihng would smoke.
What device is the only load in the control circuit of a condensing unit?
I think that would have to be some relay or contactor coil for a fan, compressor or relay contacts.
What is percentage bias relay?
This is basically a differential relay that contains an additional restraining coil with the operating coil connected at its midpoint used to prevent the unnecessary pick up of the relay.
