Electrical process interface device
摘要:
An electrical process interface device for provision in a low control and protection level of a Substation Automation or Distribution Automation system; the device includes a process interface unit for interfacing the electrical process at the low control and protection level, which unit has a number of parallel data connections on which I/O data related to control and protective devices on higher control and protection levels may be transmitted. The device also includes a signal conversion unit connected to the data connections, which unit packets data of the data connections according to a communication standard used by control and protective devices on the at least one higher control and protection level for allowing data to be directly transmitted between the electrical interface device on the low control and protection level and other devices on higher control and protection levels.
