Besides data acquisition, each local terminal has distribution switchgears 10 (20) kV. Remote terminal its own indication, with display of the monitored values. unit DT-10TSp is used in modular expandable switchgears Local terminals can be located, depending on the plant's for remote monitoring and control of complex switchgear. demands, in low voltage, medium voltage or remote part The monitoring and control functions can be extended of the plant (separate cabinet) and connected together by with functions of earth and short-circuit fault indication, optical or RS485 communication. Figure 1. shows the measurement, protection, automation, registration and Remote terminal unit DT-10TSp for monitoring and analysis of power quality and alarming. Info terminal IT-3, control grid connection of renewable energy source. The as a central unit in the system, ensures dynamic display of system includes remote monitoring, control, fault the plant’s state on the graphic LCD display and allows indication and protection. remote and local control of the switchgear. Switchgear As the Remote Terminal Unit is a distributed system, and control can be performed remotely from remote control each local terminal represents an autonomous unit (own center (radio link, Ethernet connection, GPRS or optical microprocessor, own indications-display, own power connection). Depending on the plant's complexity, besides supply), Remote Terminal Unit meets the most demanding Info terminal IT-3, Remote Terminal Unit contains various reliability and availability specifications.
