PAC-F100 is multifunction relay that have all functions, protection, control and monitoring. This relay is available by backup protection, control and monitoring of distribution line, transmission line and transformer irrelatively to grounded system(earthed network, unearthed network and resistance earthed network etc.) of system, and to distribution power-system because has directional detection element applicable. PAC-F100 has various measuring and monitoring function such as quantity of electricity measure, self-diagnosis, current input circuit monitoring, current/voltage unbalance monitoring, PT fuse monitoring and Trip Circuit Supervision (TCS). PAC-F100 has four setting groups for protection, and change and apply setting group according to system driving condition change and enables optimum protection. This relay can be various and designs economically trip logic, inter-lock sequence and lock-out function without external addition logic or connection by programmable logic(Easy-Logic). Event and waveform recording function of PAC-F100 offer driving history of necessary data and device to fault analysis. PAC-F100 has event and waveform recording data that is stored even if control power is lost. Stored recording can analyze in PC after upload using front communication port in integration PC program (PACManagerTM). If min/max value is inputted through analog input, MIN/MAX recording function of PAC-F100 is recorded quantity of electricity by primary value with inputted time, and recording is kept even if control power is lost. PAC-F100 has 8 basic LEDs and 8 user setting LEDs, and offers convenient menu-tree through graphic LCD, and relay and circuit breaker can be controlled by keypad. There is one RS-232 port on front of PAC-F100 that can communicate with PC program (PACManagerTM), and are two RS-485 ports on rear of PAC-F100 can connect with remote monitoring system. This relay provides ModBus, DNP3.0 and IEC 60870-5-103 protocol for communication with remote monitoring system.
