Transformer
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. It is used to change the voltage levels in alternating current (AC) electrical systems, enabling efficient transmission and distribution of electrical power over long distances. Transformers are fundamental components in power systems, electrical distribution networks, and many other applications.

Types of Switch Gears

  1. Low-Voltage Switchgear:

    • Operation: Designed for use in systems with voltages up to 1,000 volts. Includes devices such as circuit breakers, fuses, and disconnect switches used in residential, commercial, and industrial applications.
    • Applications: Power distribution in buildings, small-scale industrial processes, and protection of electrical equipment.

  2. Medium-Voltage Switchgear:

    • Operation: Used in systems with voltages between 1 kV and 36 kV. Includes devices such as air-insulated switchgear (AIS) and gas-insulated switchgear (GIS) that provide protection and control for medium-voltage distribution networks.
    • Applications: Substations, industrial facilities, and utility distribution networks.

  3. High-Voltage Switchgear:

    • Operation: Designed for systems with voltages above 36 kV. Includes devices such as GIS, oil-insulated switchgear, and vacuum circuit breakers that manage high-voltage transmission and distribution.
    • Applications: High-voltage substations, transmission lines, and large-scale power generation facilities.

  4. Automatic Transfer Switches (ATS):

    • Operation: Automatically transfers the load between the primary power source and a backup power source, such as a generator, in the event of a power outage.
    • Applications: Emergency power systems, critical infrastructure, and backup power solutions.
