Smart Electronic Through Hole PCB Assembly

     In the power industry, intelligent electronic devices including power equipment, transformers, capacitors and power system devices (such as bank microprocessors) are mainly used to represent controllers used to control electricity.

     Intelligent electronic devices receive data from sensors and power supplies, and issue control commands to circuit breakers when abnormalities in voltage, current, and frequency are detected, and control voltage levels to maintain desired levels. You can general intelligent electronic equipment, protective relays, road tap changer controllers, circuit breaker controllers, capacitor bank switches, recloser controllers and other voltage regulators. These are usually controlled by configuration files.

     Digital protection relay is the most important relay. Its protection function executes the control function by using microprocessors. Typical IED has about 5 to 12 protection functions, and 5 to 8 to control the control function of a single device, automatic overlapping function, self -monitoring function, communication function, etc.

     Among the recent intelligent electronic devices, IEC 61850 (English version) also meets design standards. This standard involves the automation of substations and provides interoperability and advanced communication functions.
