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

Difference between current transformers and Potential transformers

Current transformers (CT) and Potential Transformers (PT) are instrument transformer types used to step down transmission or distribution line voltages and current to the level that can be measured using measurement devices or controlled using control devices. The principle of operation of a certain type of CT and PT is similar to power transformers. Here … Read more

Difference between PLC and DCS

In the world of industrial automation, Programmable logic controllers (PLC) and Distributed Control Systems (DCS) are used to control or automate a process or a machine. They monitor the field signals and operator inputs and make decisions based on how they are programmed. Here you can understand the difference between PLC and DCS. What is … 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
