KEPCO current transformer

KEPCO current transformer

1 Transformer. A transformer is a device that boosts or decreases the voltage of alternating current. Substations employ large transformers, with those utilized for extra-high voltage sometimes reaching 500 tons. Utility poles are equipped with pole-mounted transformers that reduce voltage to 100 or 200 volts for the delivery of electricity to ...

    No load current is flowing due to open circuit. When no load current flows, there is no voltage drop and reactive drops across resistor and inductors respectably. Voltage drops across primary terminals are negligible. In second scenario, the transformer is loaded i.e. there is a load connected to the secondary terminals of the transformer.

  • DC Power Supply - testmart.com

    The direct current (DC) is usually used to power the internal circuits of an electronic device, such as a computer. A simple AC powered linear power supply uses a transformer to convert the alternating current from the wall to the desired voltage. An array of diodes then rectifies the alternating current to direct current.
