What is Buchholz Relay? The transformer is safeguarded against internal faults by the Buchholz relay. It is the relay with gas actuators. Between the conservator and the main tank is where the Buchholz relay is located. Such a relay is utilised in transformers with a rating more than 500KVA. Due to financial factors, it is …

What is Neutral? The term “neutral” refers to a point with zero potential. Because each single phase load requires the current return channel, the perfect ground point is called Neutral. To maintain a continuous flow, the electron should travel from source to load to source. As a result, it necessitates a flawless return path. If …
What is Power Factor? The power factor in an AC electric power system is defined as the ratio of real power flowing to the load to perceived power in the circuit. It is a dimensionless number between 0 and 1 (sometimes written as a percentage, such as 0.5 pf = 50% pf). The capacity …
What is a Contactor? A contactor is an electromagnetic switch that is used to turn on and off an electrical circuit. It’s also a device that can be controlled from a distance. It should be able to make, carry, and break currents in normal and operational overload circumstances. It’s closest to the load centre. It is …
What is Three Phase? A typical technique of alternating-current electric power generation, transmission, and distribution is three-phase electric power. It is a form of polyphase system that is utilised by electrical grids all over the world to transfer power. Large motors and other heavy loads are also powered by it. Because it utilises less conductor …
What is Two Phase? Two-phase electrical power was an optional process (polyphase)Â alternating current electric power distribution technology used in the early twentieth century. Two circuits were employed, with voltage phases that differed by a quarter of a cycle, or 90 degrees. Typically, four wires were utilised in circuits, two for each phase. Three wires were …
What is an ELCB? Earth Leakage Circuit Breakers are safety devices that provide additional protection against earth leakage. ELCB is employed in places where the earth impedance is high. The primary objective of these devices is to reduce the risk of shock in the event of a current flow to the earth. When energy “leaking” …
What is Circuit Breaker? A circuit breaker is a device that may manually or automatically break a circuit under all circumstances, including no load, full load, and short circuit. A circuit breaker is a device that can perform any of the following functions: Under typical circumstances, manually or by remote control, makes or breaks a …

What is a stepper motor? A stepper motor is also called a step motor because it is a pulse-driven motor that would change the angular position of the motor in steps. The stepper motor would rotate at a specific angle of degree according to the electric pulse. Basically, it is a brushless synchronous electric motor …
