The life of electrical insulating materials gets adversely affected by the rise in temperature. Average insulation life gets halved for every 10° C increase in temperature. Therefore, the classification
A hysteresis loop is a graph in a four-quadrant that shows the relationship between the induced magnetic flux density B and the magnetizing force H.
The differential relay is used for the protection of the transformer, alternator, and large-rating HT motor. The differential protection scheme is also known as zone
This article describes why the power in pure inductive and capacitive circuits is zero. The inductors and capacitors are the basic building blocks of an
Ohmic Vs. non-Ohmic Conductors The difference between ohmic and non-ohmic conductors can be found by knowing the relationship between voltage and current. When the voltage
The induction motor and the transformer work on the same principle, that is, Faraday’s law of electromagnetic induction. The motor is rated in kW instead of KVA,
kW is the unit of active power that is consumed by the load for doing real work. The real power drawn from the system is
Semiconductor fuses are used for short circuit protection of semiconductor devices like Silicon Control rectifiers (SCRs), Insulated Gate Bipolar Devices(IGBTs), diodes, triacs, thyristors, and similar
What is eddy current? When the conductor is placed in the varying magnetic field, the localized current starts flowing in the conductor, which is called
Definition of Resistance The property of the substance to resist the flow of electric current through it is known as resistance. The unit of resistance
