The role of current transformer

- Jan 25, 2021-

From the wires that pass large currents, small currents are induced in a certain proportion for measurement, and can also provide power for relay protection and automatic devices. First select the appropriate current transformer, and then pass the cable through the current transformer. At this time, the current transformer will induce current from the cable, and the magnitude of the induced current is just reduced by a certain multiple. Send the induced current to the meter for measurement, and then multiply the measured result by a certain multiple to get the true result.
