A step up transformer is an electrical device used to convert low-voltage (LV) electricity to high-voltage (HV) electricity. It consists of two or more coils of wire wound around a magnetic core. The primary coil, connected to the input, receives the low-voltage electricity. The secondary coil, connected to the output, delivers the higher voltage electricity….
A step down transformer is a type of electrical device that is used to convert high voltage (HV) electricity to low voltage (LV) electricity. It consists of two or more coils of wire wound around a magnetic core. The primary coil, connected to the input power source, receives the high-voltage electricity. The secondary coil, connected…
Transformers are fundamental components in electrical systems, playing a crucial role in power distribution, voltage regulation, and electrical isolation. Understanding the working principle of transformer is essential for anyone studying or working with electrical systems. In this article, we will delve into the intricacies of how transformers function in electrical applications. The Working Principle of…
An electrical transformer is a static device that transfers electrical energy between two or more circuits through electromagnetic induction. It consists of two or more coils of insulated wire, known as windings, and a magnetic core that provides a path for the magnetic flux. The primary winding receives electrical energy from the input source, while…
1 unit of electricity is an important parameter for understanding the energy consumption by the electrical load. A Watt (W) is the standard unit of power or load. The watt(W) is the rate of energy transfer over a unit of time. 1 kW =1000 W. When a 1 kW load is running for 1 hour…
A Snubber circuit is an essential part of an electronic circuit that is used to protect sensitive electronic components from voltage spikes or transient faults. It is consisting a series combination of resistor and capacitor and which is always connected in parallel with the protected part of the circuit. Generally, Snubber Circuit is used in…
The nature of the works of the Isolator and Circuit Breaker is the same, both are used to isolate the circuit from the connected supply. The operating characteristics of both the equipment are different and based on the requirement they are used in a different locations in electrical switchgear. What is Isolator? The isolator is…
DC earth fault relay is commonly used to detect earth fault in DC systems. An ungrounded DC system is used to control the supply of protection systems, control panels, communication, and other networking devices. When one terminal of the DC system is grounded, it is not creating any problem. However, when both the DC terminal…
DC earth fault locator is an instrument that is used to detect earth fault in a live DC system. DC system is used for the running of protection systems in substations, generating stations, communication & networking equipment, and other electronic devices. Due to cable insulation failure or wrong wire connection, the DC terminal can be…
Anti pumping relay is used in the circuit breakers to prevent unwanted closing of the breaker after immediate tripping. Due to failure of the TNC switch (Trip normal close) or any other discrepancy in the CB closing circuit, continuous CB close command can be extended to the closing coil. In that condition, after tripping the…
