Potential transformers (PT) or voltage transformers are instrument transformers used for voltage measurements. They are connected in parallel to the line and operates under the same principle of power transformers.…
What is a current transformer? A current transformer is a type of instrument, used to measure or sense large alternating currents by scaling it to a smaller, safer and measurable…
Some amount of power is lost during the voltage transformation process in a transformer. The current flows in a transformer winding and the alternating magnetic field in the core contributes to the majority of transformer losses.
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…
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…
Electromagnetic induction is a phenomenon by which electromotive force is produced across a conductor placed in a varying magnetic field. It was discovered by Michael Faraday in 1831 after performing…
Michael Faraday discovered the phenomenon of electromagnetic induction in 1831 which was a major breakthrough and led to the invention of electric motor and generator. Faraday's law of electromagnetic induction…
Heinrich Friedrich Emil Lenz was a Russian physicist, working at the University of St. Petersburg, Russia. He formulated Lenz's law in 1834. This law predicts the direction of the current…
The terms, motor rated current, full load current and nominal current, are very likely to confuse electrical engineers. Even though these terms are quite similar, there are slightly different from…
Motor rated current also known as full load amperes (FLA) of a motor is the maximum current the motor windings are designed to carry. Here is a simple motor rated…
