Technical details and manufacturing context for Control Power Transformer (Optional)

Definition
An optional electrical component within the Starter Bucket (Unit) designed to step down and isolate the main power supply voltage to a lower, stable voltage suitable for powering sensitive control circuits, relays, contactors, and instrumentation, ensuring reliable operation and protection of the control system.
Working Principle
Operates on the principle of electromagnetic induction. When AC voltage is applied to the primary winding, it creates a varying magnetic field in the core. This field induces a proportional AC voltage in the secondary winding, stepping the voltage down to the required control level while providing electrical isolation between the primary (main power) and secondary (control power) circuits.
Common Materials
Silicon Steel Laminations, Copper Windings, Insulating Varnish, Protective Enclosure
Technical Parameters
  • Rated power capacity of the transformer. (VA/kVA) Customizable
Components / BOM
  • Core Part
    Provides a low-reluctance path for the magnetic flux, typically made of laminated silicon steel to reduce eddy current losses.
    Material: Silicon Steel Laminations
  • Primary Winding Part
    The input coil connected to the main power supply, where the alternating current creates the varying magnetic field.
    Material: Copper Wire
  • Secondary Winding Part
    The output coil where the stepped-down voltage is induced, supplying power to the control circuits.
    Material: Copper Wire
  • Insulation Part
    Electrical insulation between windings and between windings and the core to prevent short circuits and ensure safety.
    Material: Insulating Paper/Varnish
  • Terminal Block
    Provides secure connection points for input and output power cables.
    Material: Thermoplastic/Composite
