Large and small current in the power supply electric circuit voltage difference from several to tens of thousands of AnDouYou Ann. For convenience of secondary instrument measuring need into a more uniform current, in addition line voltage is high, such as direct measurement is very dangerous. Current transformer is current 3 phase ac induction motor transformer and electrical isolation effect. Earlier, most of display instrument is a pointer type current meter, so the current transformer secondary level most of the electric current is the ampere (e.g., 5 a, etc.). Now wholesalemotor.blogspot.com most of the power measurement, digital and computer sampling signal is commonly milliamperes (0 to 5 v, 4-20 ma, etc.). Micro ct (current transformer) secondary current as milliamperes, between the main transformer and sampling. Micro current transformer has also been called "instrument use current transformer". (the instrument with a current transformer with a layer of meaning is using more current than Induction motor the precision of the current transformer in the laboratory, is generally used electric motor in expanding instrument range.)
