Current Transformers

Current Transformers can be found in electrical engineering. They measure electric currents. They are also known simply as instrument transformers. They produce a current proportional in magnitude to the current in the circuit. This can then be connected to recording and measurement instruments. In managing electricity infrastructure, all needs must be wise and with quality products. Then MGM Transformers can help to supply varying secondary voltages to externally connected loads. You can find quality electrical and lighting products at the MGM Transformer Company.

These transformers also have the ability to isolate the measuring instrument from very high voltages in a primary circuit. These transformers are commonly used in the electrical power sector for metering or protective relays. As other transformers, these have a primary and secondary windings.

Current transformers serve two primary purposes: They ensure that primary and second circuits are well-coupled, so that the secondary voltage has an accurate relationship to the primary circuit.

Other types of electrical transformers are:

o Power Transistors

o Control transformers

o Dry type of transformers

o High voltage Transformers

o Three phase transformers

o Step-down transformers

Current transformers are used for many purposes. Some devices are used for street lighting. Others can be used to measure current within electronic equipment and motors. These are small-sized current transformers that are mounted on printed circuit board and are used for sensing overloads of current.

Three-phase systems often use larger devices to measure voltage or current. Commercial transformers measure low power currents. Some transformers can withstand weather and are suitable to be outdoors.

There are 2 basic types for current transformers.

o Wound

o Toroidal

Wound transformers contain an integral secondary winding which is connected with the conductor carrying the measured voltage.

Toroidal current converters do away with a primary wire. Instead, current is carried through a Toroidal transformer window.

A current converter is a type o instrument transformer designed to supply a current to its secondary in proportion to the primary.
