Transformers are used for increasing, decreasing, measuring voltage, and other purposes. There are many kinds of transformers. Several transformers are used for several purposes. From many transformers, the current transformer is one kind of measurement transformer. It is used to measure the high voltage.
Definition of Current Transformer
The current transformer converts high voltage to low voltage, calculated by observing the ammeter. In this transformer, the primary and secondary currents are proportional. The measurement range of this transformer is 0 to 100 volts. Current transformers are used with AC instruments, meters, or control devices.
Another form of instrument transformer is the current transformer. Current transformers are used with protective devices. An almost zero angle separates the primary and secondary currents.
