A certain amount of current is drawn by a transformer from the source connected to it primary even when no load is connected to its secondary. A part of this…
kW and kVA are units of power. kW stands for kilo-watts and kVA stands for kilo-volts ampere. Let's see what is the difference between kW and kVA and how to…
kVA stands for kilo volt-amperes or simply 1000 volt-amperes. It is basically the unit of apparent power and is the product of RMS values of voltage and current. One kVA…
Induction motors are one of the major power-consuming load on the planet today and are widely used for all industrial and domestic applications. Plugging is one of the braking technique…
Short circuits and overloads are abnormal conditions that cause heavy current flow in a circuit. Heavy currents are capable of damaging a device or a circuit and may end up…
Circuit protection devices such as fuses and MCBs are used to safeguard any equipment from damages caused due to short circuits. The usage of these devices does not mitigate the…
Relays are electrically operated switching devices, used to gain control over processes and circuits. Based on their principle of operation they are classified into two types: Solid-state relays and electromechanical…
Earth fault is an undesirable condition at which current flow from a conductor to earth. This can happen when a current-carrying conductor falls on the ground or the body of…
