Wave Trapper: A wave trap is an interference positioned on the transmission line that stops a high-frequency waveform from entering a low-frequency device. A cylindrical shape characterises the wave trap. Line trap and High-frequency stopper are some other names for wave traps (2Khz to 250Khz). We can describe the wave trap as a low pass …

What is Changeover Switch? A switch used to transfer the source of power supply to an electrical load is known as a changeover switch. Changeover switches are available in a variety of forms. It is divided into two types based on the operation: 1. Manual 2. Automatic The transfer switch is also known as the …
What is Excitation System? Excitation is the technique of creating a magnetic field using an electric current. An excitation system’s primary job is to supply direct current to the synchronous machine field winding. The excitation system regulates the field voltage and field current to carry out control and protective tasks necessary for the power system …
What is Transformer Oil Testing? Transformer oil testing is analogous to blood testing for people. Transformer oil testing is one of the most well-known and effective loss prevention strategies, and it need to be a part of each organization’s maintenance schedule. In addition to serving as an early warning system, it also enables us to …

Circuit diagrams virtually represent electrical symbols or electronic circuitry. The parts of a circuit are represented by a few common symbols. Some of the symbols that are widely used for designing circuits. To represent fundamental electrical or electronic devices, a variety of electrical and electronic schematic symbols are employed. Typically, apply these to build circuit …
What is a Relay? Relays are switching devices that are used to control the flow of electricity, and by extension, the circuit to which it is directed. By managing the current flow through an electromechanical assembly or a solid state circuit, a relay can be used to switch a circuit and activate/deactivate among several connected …

What is Alternator? A machine that transforms mechanical energy into electrical energy in the form of alternating current at a particular voltage and frequency is referred to as an alternator. Synchronous generators are another name for alternators. The only form of energy that is converted is an alternating current. Most alternators use a spinning magnetic …
What is a Transformer? Electrical power is transformed from one circuit to another circuit using a static electrical device called an electrical transformer without affecting the frequency. Transformers have the ability to change the voltage while also altering the current. AC current is used for transmission. The transformer operates on the core concepts of electromagnetic …

What is Moulded Case Circuit Breakers (MCCB)? An electrical MCCB is a moulded case circuit breaker in its entire form. MCCBs are automatic electrical devices that guard against overload, short circuit, sudden overcurrent, and earth faults in electrical equipment. It is an improved MCB version (Miniature circuit breaker). With a voltage range of 230V to …
