Wiring of control power transformer for motor control circuits | EEP - The schematic symbol for the transformer is represented by means of two agencies of “scallops” dealing with each other. Those constitute the primary and the secondary windings. The winding with the better variety of turns ought to be proven to have greater scallops than the opposite to discover it as both a step-down or step-up transformer. An ordinary manipulate transformer is shown in determine 1 beneath. It includes separate coils of twine (windings) located adjoining to every other on a not unusual iron center. Be aware that the primary winding is attached to the electricity source. The secondary winding is hooked up to the control circuit. The motive of the transformer is to switch electric powered energy from the primary circuit to the secondary circuit. When you are putting in a manage electricity transformer right into a starter, you should ensure that the magnet coil is rated for the identical voltage because the secondary of the transformer.?similarly, any pilot lighting fixtures on this circuit should have the identical voltage because the secondary.

The relationship of the voltage across the primary to the voltage throughout the secondary is in direct share to the number of activates each windings.?as an example, one hundred turns at the number one, and 10 turns on the secondary, is a ten to one ratio. If the primary is 500 volts, we can get 50 volts on the secondary. This produces a magnetic field that extends outdoor the winding, inside the form of concentric loops as proven in parent 2. The magnetic field fluctuates because the ac changes course. Those magnetic strains reduce throughout the conductors of the secondary winding and set off a voltage. The motor department circuit is often a section of a larger electric distribution community in an industrial plant. The motor circuit components the specified strength to the numerous manage devices in order for them to function. In some cases, the diverse control gadgets are operated on the equal voltage as the motor.

Put off cord “c”, if provided, from starter’s manipulate circuit.?as discussed in advance on this guide, if wire “c” is provided on the starter (magnet coil voltages extra than 120v), you need to remove it. This could convert the starter from commonplace control to separate manage.
