3 Phase Transformers
What is a 3 Phase Transformer? A three-phase transformer often represented as a 3 phase or 3ɸ transformer, is made up of three primary coils and three secondary coils. A 3 phase transformer can be built by using three identical single-phase transformers, also known as...
The Art of Crafting Copper Bus Bars
Copper bus bars are vital components in electrical and power distribution systems, serving as efficient conduits for current transmission. This article will explore the world of copper bus bar fabrication, highlighting its significance and key considerations. From...
Low Voltage Three Phase Transformers
Low-voltage three-phase transformers are electrical devices that transfer electrical energy from one circuit to another through electromagnetic induction. They are used to step up or down voltage levels in three-phase electrical systems, commonly used in power...
Why Choose Johnson Coil for Custom Inductors?
There are many advantages to selecting custom inductors for your electrical or electronic products. Most important, custom-design means you get—and pay for—exactly what you need: no more, no less. Using custom-made components helps you avoid many common problems, and...
How Toroidal Electrical Transformers Work
Electrical transformers are essentially a coil of electrically conductive wire wound around an iron core, most often a rectangular “EI” core. Some transformers, however, look more like a doughnut, and they are called toroidal transformers. Either construction makes...
Transformer Manufacturers – Why Choose Johnson Electric Coil Company?
Many kinds of electrical or electronic components and circuits require lower voltages than line voltage and therefore a means to lower it. Some applications and circuits are more complicated, sophisticated, or sensitive than others. For some, the best solution may be...
What is the Purpose of an Electrical Transformer?
A transformer is an electrical device designed and manufactured to step voltage up or step down. Electrical transformers operate on the principle of magnetic induction and have no moving parts. As a transformer transforms the voltage on the input side to the voltage...
