Isolation Transformers: Working and Important Applications

Posted on

Isolation transformers serve the galvanic isolation in electrical systems by isolating the circuits supply and and secondary side. In single phase electrical wiring, there are three wires hot, neutral, and ground. When there are numerous physically separated devices are connected in the same circuit they may use a similar power line.

DC Current Transformer Working Principle: Important Concepts

Posted on

At the heart of the DC current transformer working principle is its core and coil arrangement. Similar to AC transformers, DC current transformers consist of a magnetic core and primary and secondary windings. The primary winding, typically consisting of a single turn or a few turns of a thick conductor, is connected in series with the DC circuit carrying the current to be measured.

What is Hysteresis loss? Magnitude Formula

Posted on

Hysteresis loss, also known as magnetic hysteresis loss, is a phenomenon that occurs in ferromagnetic materials when they are subjected to cyclic magnetic fields. It refers to the energy dissipated in the form of heat as the magnetic domains within the material undergo repeated alignment and realignment with the changing magnetic field. Hysteresis is a significant factor to consider in various electrical and magnetic applications.

Eddy Current Loss: Important Applications & Expression

Posted on

Eddy current loss, also known as Foucault or joule loss, is a phenomenon that occurs when a conductor is exposed to a varying magnetic field, resulting in the generation of circulating currents within the conductor. These circulating currents are known as Eddy currents and are responsible for the dissipation of energy in the form of heat. Eddy current loss can have significant implications in various electrical and magnetic systems.
