Electric current collectors

What are current collectors? Current collectors are components fitted to an electric equipment in motion to collect electric current required for its operation from a stationary busbar. They can be found in electric locomotives, cranes, trams, overhead conveyors, travelling cranes etc. Another place where you may see them is in those bumper cars in amusement … Read more

Difference between volts and amps | Volts vs amps

Volts and amps or ampere are two measures of electricity. Specifically, voltage is the measure of electric potential difference between two points whereas ampere is the measure of electric current. They are closely related terms and can be a bit difficult to understand. In this article, let’s learn the difference between volts and amps. What … Read more

Ultimate breaking capacity (Icu) and Service breaking capacity (Ics) – IEC 60947-2

Circuit breakers are devices that can protect circuits or loads during overloads and short circuit. The reliability of the circuit breakers during short circuits is determined by Ultimate breaking capacity (Icu) and Service breaking capacity (Ics) ratings. These ratings are mentioned in IEC/EN 60947-2. Definition of Ultimate breaking capacity (Icu) The term Ultimate breaking capacity … Read more

What is induced current?

Electromagnetic induction occurs whenever there is a relative motion between a magnetic field and a coil. The electromagnetic force acts on the charged particles inside the coil, forcing them in one direction along the coil. If ends of the coil are closed, it results in a current flow. This current is known as induced current. … Read more

Electric Current and Current Flow

To understand the basics of electricity it is necessary to understand the concepts of electric charge and current. Electrically charged particles are present in every matter in the universe. The unique property of these charged particles is that it can move on the application of an external force. This article aims to help you understand … Read more

What is a short circuit?

A short circuit is a situation in which two or more different lines (having different voltage levels/ different phase/ different terminals) come in contact and finally leads to the flow of large short circuit currents that may damage the equipment or the system. In a three-phase system, a occurs when two or more phases come … Read more
