-The user can set appropriate statistical control standards for each site with various information (receiving surge inflow, overvoltage recovery, leakage current status, site voltage status, temperature, and communication status) as well as actual SPD status information (normal, replacement notice, replacement) at the site. No such management techniques have been used yet, and examples of SPD's alarm and information transmission of magnetic states, including all of these various information, require very complex magnetic state checks and processing. It is also important to select a communication protocol for simultaneous health checks of composite SPDs. It cannot be used for Smart Grid with 1:1 communication. This facility supports RS485/Ethernet communication methods with ModBus protocol, which is most commonly used in industrial sites.
- As SLPMS SPD, SPD is rated I that can protect direct lightning as well as indirect/intrusive mines, and this agency is the only company that has obtained international CB certification and domestic KS certification from Iimp 100kA in Korea, and the record continues for five years since 2014 and is expected to exist as a leading technology for a considerable period of time thereafter. Few foreign companies have Iimp 100kA certified products. In this project, we would like to emphasize the excellence of direct lightning protection at smart grid sites, but we would like to consider the economics of the sites, so we would like to develop the surge protection rating of SPD into Iimp 50 kA by applying LPL III-IV rating criteria with external and internal lightning capacity of 100 kA in the specification. No such development has been proposed for smart grids. By applying this, smart grid sites will be equipped with a minimum level of direct lightning protection, which will prevent disasters caused by direct fire at the industrial sites concerned.
