ATO Current Transformers are the instrument that converts a large current (100A/200A/400A/600A/1000A/2500A/3000A) on the primary side into a small current (5A/1A/500mA) on the secondary side for measurement based on the principle of electromagnetic induction. In the lines of power generation, power transformation, power transmission, power distribution and power consumption, the current size varies greatly, ranging from a few amps to tens of thousands of amps. In order to facilitate measurement, protection and control, it is necessary to convert the current on the line into a relatively uniform current. In addition, the voltage on the line is generally relatively high, so direct measurement is very dangerous. ATO Current Transformer plays the role of current conversion and electrical isolation.

Besides, ATO Split Core Current Transformers are used for measuring alternating current (AC) in electrical systems. They consist of a core that can be split into two halves, allowing them to be easily installed around existing conductors without the need to disconnect the circuit.
