    Product Details

    Working Principle

    The Distribution Transformer operates on the principle of electromagnetic induction. It consists of primary and secondary windings mounted on a laminated silicon steel core. When alternating current flows through the primary winding, it creates a varying magnetic field in the core, which induces a voltage in the secondary winding. The voltage transformation ratio is determined by the turns ratio between the primary and secondary windings. Typically installed on utility poles (pole-mounted) or at ground level (pad-mounted), these transformers are filled with insulating oil that serves both as a dielectric medium and as a coolant, dissipating heat generated by core and copper losses to maintain optimal operating temperatures.

    Frequently Asked Questions
    Q What is the working principle of a distribution transformer?
    A distribution transformer works on the principle of electromagnetic induction. When alternating current passes through the primary winding, it generates a varying magnetic field in the laminated silicon steel core, which then induces a corresponding voltage in the secondary winding. The ratio of turns between the primary and secondary windings determines the output voltage level.
    Q What are the main types of distribution transformers?
    The two most common types are pole-mounted transformers, which are installed on utility poles for overhead power lines, and pad-mounted transformers, which are installed at ground level in a tamper-resistant enclosure. Both types are oil-filled for insulation and cooling purposes.
    Q What international standards do your distribution transformers comply with?
    Our distribution transformers are designed, tested, and manufactured in full compliance with IEC 60076 and other relevant international standards. This ensures product safety, interchangeability with other grid components, and full compatibility with utility grid requirements worldwide.
    Q How does the insulating oil in a distribution transformer function?
    The insulating oil inside a distribution transformer serves a dual purpose. It acts as a dielectric medium to provide electrical insulation between the windings and the tank, and it also functions as a coolant by absorbing and dissipating heat generated by core and copper losses, helping maintain optimal operating temperatures.
    Q Can distribution transformers be used in solar rooftop systems?
    Yes. Distribution transformers are widely used in grid-tied solar rooftop installations. They provide essential voltage matching and electrical isolation between the photovoltaic (PV) arrays and the utility grid, ensuring safe and efficient integration of solar-generated power into the distribution network.
    Q How do distribution transformers handle short-circuit conditions?
    The windings of our distribution transformers are uniformly supported and mechanically braced to withstand the high electromagnetic forces generated during short-circuit events. This robust construction prevents winding deformation and ensures the transformer can continue reliable operation even after repeated fault conditions.
