Frequently Asked Questions
Transformers are used in a variety of applications, including power generation, transmission and distribution, lighting, audio systems, and electronic equipment. Power generation: Transformers are used in power plants to increase the voltage of the electricity generated by the plant before it is sent to the grid.
Current transformers have many uses, including providing overload protection for equipment operating at high currents; monitoring power usage; controlling motor speed; measuring voltage drop; and providing feedback for automated systems such as those used in industrial automation applications.
An isolation transformer is a type of transformer used to transfer electrical power from a source to a device while isolating the powered device from the power source for safety and performance reasons.
