Pylons are an integral part of everyday life, and whilst many people complain about their “ugliness”, they perform essential functions that enable the population to have electricity in their homes and ...

A current transformer (CT) is a simple, practical and inexpensive means of detecting the presence of AC current. Detecting load current rather than applied voltage is a superior method of determining ...

It is important for machine design engineers to understand how transformers work so they can design machinery that operates optimally within the proper voltage ranges, as well as select the right ...

Note: This article is based on the 2020 NEC. A transformer transfers electrical energy (power) from one system to another by induction, with no physical connection between the two systems (other than ...

When signal current goes through the primary winding, it generates a magnetic field which induces a voltage across the secondary winding. Connecting a load to the secondary causes an AC current to ...

step-down transformers decrease the voltage. The transformer in the diagram above is a step-down transformer – there are fewer turns on the secondary coil than on the primary coil. Type of transformer ...

Omicron has introduced a way to test current transformers at all lifecycle stages by using a testing method called "the modeling concept". The "traditional" way of testing a current transformer is to ...
