The SEFI-4 .5 Versatile Panel Fault Indicator
Product description: The SEFI-4.5 versatile panel fault indicator is widely used in RMU, cable branch box and the box changes for a realtime detection of load current, zero-sequence current and the temperature of cable connector. Through the signal line to pass the data to the host,display values on OLED screen on the front panel in order to know conditions of the load current, zero sequence current and the temperature of cable connector. When a short circuit, ground fault and overheating occur, current or temperature exceeds the setting value, OLED screen displays the fault status and records, the indicator gives a fault indication, through remote communication interface
to upload fault information, the staff based on fault information quickly find fault line and position, timely solve the problem and restore the power. With the improvement of the continuous development of urban and rural power systems, the product has become essential advanced equipment in urban and rural power net. This product includes a host, the three-phase current / temperature sensor, a zerosequence current sensor and four signal lines. Host can provide RS232/RS485/RS422 communication interface, selectable baud rate from 300bps to 115200bps, start / stop bits / parity optional, RTS / CTS flow control optional. Can be composed of GPRS wireless or wired network.
