There is a lot of confusions and misinterpretations regarding the difference between relay and contactor around the industry as they are two closely related terms. Many times these two terms are used nearly interchangeably. Both of them are electrically operated switches and mainly used for control and switching of loads. Although the basic principle of … Read more
Relays and circuit breakers are two commonly used terms of a power system. The study of the protection in power systems is incomplete without the study of relays and circuit breakers. The uses of relays and circuit breakers are found in industrial as well as in commercial applications. There are many differences between a relay … Read more
Cables that are usually known as coaxial cable, or simply coax, need crimping to be done before you can use them. This is because these cables are basically used to deliver signals, and are highly sensitive to outside interference. If you use a connector with the cable head, the chances of interference lessen. That’s why … Read more
Arc chute is a set of parallel arranged metal plates which extinguishes the arc formed when the circuit breaker interrupts the high electric current. It is also known by other names such as arc dividers or arc splitters. It is an important component of the circuit breaker. These metal plates have an equal air gap … Read more
A high voltage detector is a device which detects the presence of high voltage without any physical contact with the conductor. It is used to determine whether the conductor is energized or de-energized so that it can be earthed before starting maintenance work. Hence it gives information to the operator whether it is safe to … Read more
If we assemble one or more wires side by side or make a bundle of it that is used to transfer electric current, it is called electric cable. The composition of one or more than one of these cables is known as cable assembly. We can build a cable tree or cable harness using a … Read more
Electrical Bus bar is an important component in the installation of an electrical distribution system. It is used for collecting current from incoming terminals of a power system and distributing it to various outgoing terminals. It acts as a junction between incoming power and outgoing power. Before going into deep in concept, let us first … Read more
In this article, we will learn important terms in Economic Aspects of Power Generation. What is Load? A device which uses electrical energy is said to impose a load on the system. What is Connected Load? The sum of continuous ratings of all loads connected to the system is known as a connected load. What … Read more
An electrical fault is a condition which can cause equipment failures (in transformers, transmission lines, alternators, busbars, etc.) and disturbs the normal working of the system. The faults can also lead to the death of humans, birds, and animals along with equipment failure and electric power supply interruption. Power system protection deals with the protection … Read more
Power system protection is a branch of electrical engineering that deals with the protection of electrical equipment (or component) in a power system network by removing the faulty part. or Power system protection deals with protecting electrical power systems from faults by disconnecting faulty components from the rest of the network. Power system protection is … Read more
