Esennar Transformers

  Star-rating transformers refer to transformers that are assigned energy efficiency ratings based on a star-rating system. This system is undertaken mainly to indicate the efficiency levels of the transformer based on established parameters, which are implemented by a regulatory body authorised by the government of the country or region. The star-rating system usually ranges from 1 to 5-star rating system, with 5 being the indicator of higher levels of efficiency. The rating system is usually based on transformers' ability to minimise energy losses during the conversion and distribution of electrical power. The transformer device can also achieve a high rating by incorporating design features, superior materials, winding techniques, optimised circuitry, reduced resistance etc. These design enhancements result in reduced core losses and overall improvement of performance, which leads to lower power consumption. With the implementation of this system, companies adhere to its guidel

  A single-phase transformer is a type of electrical transformer designed to transfer electrical energy between two circuits by using a single-phase AC. It is largely used in applications involving the step-up or step-down of voltage levels. This device consists of a magnetic transformer part and copper winding, which serves as an electrical part. The primary winding is connected to the input voltage source, while the secondary winding is connected to the load or the output circuit. The operating principle of a single-phase transformer is based on Faraday’s law of electromagnetic induction. When AC is passed through the primary winding, it creates a magnetic field around the core. This induces an electromagnetic force (EMF) in the secondary winding, which is connected to the load or the output circuit. The power of the voltage depends on the turn ratio between the primary and secondary windings. The magnetic flux generated by the primary winding causes voltage generation in the seconda
