Boot-KDM is a type of auxiliary device used to provide overload and short circuit protection for electrical system. It is widely used in the high-voltage and low-voltage electrical system, such as power distribution network, communication network, industrial and mining system. Boot-KDM consists of two parts: the Boot-KDM main controller and the Boot-KDM accessory module.Boot-KDM accessories include current transformer, voltage transformer, relay, trip unit and other related parts. The current transformer can detect current changes on the power line, while the voltage transformer can detect voltage changes. The relay acts as a switch in the system, either isolating and tripping the line or resetting it after a fault has occurred. The trip unit is a set of electronic components that are connected to the relay and can detect faults such as short circuits and send signals to the main controller to trip the line.The working principle of Boot-KDM can be described as follows. After a voltage or current beyond the rated value is detected by the current transformer or voltage transformer, the relay is switched on, and the trip unit is turned on. The trip unit then sends a signal to the main controller to trip the line so that the fault can be isolated from the system. After the fault is eliminated, the main controller can reset the relay and trip unit to restore the system.To sum up, Boot-KDM application field covers both high voltage and low voltage electric power distribution network, communication networks, and industrial and mining systems. Its working principle is based on the electric current and voltage transformer to detect overvoltage and current changes, the relay to switch and isolate the line, and the trip unit to detect faults and send signals to the main controller to trip the line. All these components work together to provide overload and short circuit protection for the electrical system.
