Three Phase TransformersThree phase power distribution and transmission systems require the use of three phase transformers.
Instrument TransformerHigh voltage and current cannot be measured by ordinary volt-meter and ampere meter. Instrument transformer are used for this purpose.
Parallel Operation of TransformerNeed for Parallel operationWhen load on the system is increased, it is easy to ad
Transformers TestsA number of tests are made on transformer to determine the voltage ratio, reactance of the windings, magnetizing current, core losses, copper losses, efficiency and temperature rise etc
Auto TransformerAn auto transformer has one winding only Part of this winding being common to both primary and secondary.
Diode Circuit Analysis & LossesTo analyze diode circuits, the state of the diode (on or off) must first be found. The diode can then be replaced by the switch equivalent circuit.
