1 Introduction remote RTU control GE-harrisD25 device
GE-Harris company has been in SCADA system and electric power automation technology forefront. Harris is used in the manufacturing of substation control system of D20 series, in the SCADA system in the application of open architecture and distributed processing characteristics known. D20 through the application in the global power generation, substation and distribution, successfully demonstrated that the GE-Harris advanced engineering technology. However, in order to make the substation and distribution operation is more suitable for the power user requirements. The research and development of GE-Harris remains dedicated to more advanced technology.
D25 multifunctional intelligent electronic device is used for distributed remote terminal unit substation and substation.
D25 is a I/O module and communication product distribution, an intelligent, it is a basic and very important part of substation automation and control system.
