Latching Relay : Working, Circuit, Wiring, Types & Its Applications

September 20, 2023 By Wat Electrical

Impulse Sequencing Type

Generally, normal switches are used at present to open or close an electrical circuit manually. Similarly, a Relay is one type of electromechanical switch used for connecting or disconnecting two electrical circuits. But a relay utilizes an electrical signal for controlling an electromagnet to fix or separate another circuit. Relays are used where a particular circuit or various circuits needs to control with a low-power signal. Relays are available in … [Read more...]

Electrical Wiring : Materials, Colors, Types and Their Differences

August 30, 2023 By Wat Electrical

Electrical Wiring

A wire is an electrical conductor that carries electricity where the conductor of wire is made with aluminum or copper. Similarly, a cable is a set of one or more different wires used to transmit electric current. It is necessary to know different kinds of wires & their characteristics controlled by the NEC or National Electrical Code for different installations & applications. There are many factors that need to be considered for selecting a … [Read more...]

Quality Factor : definition, Formula, Damping, Unit and Its Effects

August 21, 2023 By Wat Electrical

Quality Factor or Q Factor

The Quality Factor ‘Q’ concept was first conceived by an engineer “K. S. Johnson” from the Department of Engineering of Western Electric Company in the United States. He evaluated the quality & performance of different coils. He developed the quality factor concept during his investigation over the course. Surprisingly, his choice of selecting the ‘Q’ letter for the quality factor was made with observation. This concept was applicable in many areas of … [Read more...]

Circuit Breaker : Circuit, Working, Classification, Differences & Its Applications

August 18, 2023 By Wat Electrical

Circuit Breaker

The first compact commercial circuit breaker was launched by Stotz in 1923 which combines both the thermal & magnetic protection functions. After that, his team developed a circuit breaker device to replace a fuse. This device has a component, once it is heated it will enable a disconnecting device and once it is cooled, then it is turned on again. There are many companies that have been developing circuit breakers continually which range from … [Read more...]

Transmission Lines : Parameters, Types, Efficiency & Characteristic Impedance

August 7, 2023 By Wat Electrical

Transmission Lines

The first transmission line was demonstrated over an extended distance by physicist Stephen Gray on July 14, 1729, to show that one can transfer electricity through that method. This demonstration is used damp hemp cords which are balanced through silk threads. In 1882, electric power transmission was accomplished by the first high-voltage transmission between Munich & Miesbach. After that in 1891, the first three-phase AC overhead line construction … [Read more...]

Series Transformer : Wiring Diagram & Its Affects

July 31, 2023 By Wat Electrical

Series Transformer

Transformers are typically used to step down or step up voltage levels in AC circuits, and they operate based on electromagnetic induction. When transformers are connected in series, each transformer's primary winding is connected in series with the previous transformer's secondary winding. The secondary winding of the first transformer is connected to the load, and the primary winding of the last transformer is connected to the power source. In electrical … [Read more...]

Vacuum Circuit Breaker : Diagram, Properties, Construction, Working & Its Applications

July 25, 2023 By Wat Electrical

Vacuum Circuit Breaker Construction

A circuit breaker is one type of electrical switching device used to control & also protect the power system, either automatically or manually from any harm occurred by short circuits or overload. The main function of the circuit breaker is to obstruct the flow of current once the protective relays notice a fault like electrical fires, shocks, and the electrocution risk. These are classified into different types based on different factors, location of … [Read more...]

Power Transformer : Construction, Working, Differences, Selection, Failures & Its Applications

July 24, 2023 By Wat Electrical

Power Transformer

A transformer is normally an electrical device used for increasing or decreasing the voltage supply without changing the frequency of AC between two circuits. Similarly, a transformer that functions with high voltages & currents within the power system network is known as a power transformer. This transformer is used to change bulk electrical energy from one frequency to another. Power transformers are very important devices to transmit, distribute, … [Read more...]

Isolation Transformer : Construction, Working Principle, Types, Advantages & Its Applications

July 17, 2023 By Wat Electrical

Isolation Transformer

In power systems, transformers are electrical machines used for transferring one form of energy to another form without modifying frequency by stepping up/down the main voltage. Similarly, a transformer that is used to isolate circuits is known as an isolation transformer. The primary voltage value in this transformer will be equivalent to the secondary voltage but the windings in this transformer will have an equal number of turns to balance for losses. … [Read more...]

Single Phase Transformer : Construction, Working, Wiring, Problems & Its Applications

July 10, 2023 By Wat Electrical

Single Phase Transformer

A transformer is a stationary electrical machine mainly used to change electrical power from one circuit to another without varying the frequency. Transformers mainly increase or decrease the voltage with an equivalent increase or decrease within the current. The transformer works on the principle of mutual induction occurrence between two transformer windings connected through the common magnetic flux. Transformers are classified into different types … [Read more...]
