Transformer USES: 1, the voltage transformer is a kind of voltage changer, voltage transformation and isolate the twofold effect, it will be high pressure loop or low voltage circuit of high voltage to low voltage ( General is 100 v) , supply meter and relay protection device to realize measurement, metering, protection, and so on. 2, the current transformer is a kind of current commutation device, has current transformation and isolation twofold effect, it will be high pressure loop or low voltage large current into a low pressure low current loop ( Generally for 5 a) , supply meter and relay protection device to realize measurement, metering, protection, and so on.
