LV Low Voltage Switchgear Components

Electrical switchgear are very important part of any electrical distribution system. Switch gears are used for many purposes like protection, isolation from live parts and switching operation. A switchgear is the combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment… Read More »

Voltage Stabilizer & How it Works

What is voltage stabilizer? Voltage stabilizer is an equipment that stabilizes voltage. The process of stabilization happens by bringing voltage to a desirable level whenever there is any kind of fluctuation in the power system. Therefore we can say that voltage stabilizer is a current regulator used to maintain and control voltage to produce a… Read More »

Electrical Busbar Protection – Differential Relay Function

Differential busbar protection is the most common and reliable scheme for the bus bar protection. Earlier there was no other option to use only conventional over current relays for busbar protection. But it is desirable that fault in any feeder or transformer connected to the busbar system should not disturb overall busbar system. Due to… Read More »

Kirchhoff’s Rules Kirchhoff’s Voltage Law – Kirchhoff’s Current Law

Kirchhoff’s Voltage Law states that net voltage gain and net voltage drops along a closed loop are equal. Kirchhoff’s Current Law states that at any point in the circuit the total current enters, is exactly equal to the total current leaves the point. There are some simple relationships between currents and voltages of different branches of an… Read More »
