The problems of controlling to the devices working in high voltage usually appear in the field of auto-controlling. It is importance and difficulty to control the devices working in high voltage and big current by programmable unit in low voltage and small current. Current transducer can change AC current into DC current , and into digital signal which can directly connect to PLC、SCM、PC etc. it is simple to finish controlling work on it. Current transducer plays a very important role in the course. This is an example of use of current transducer in automatic control system in pumping station.
