    Small Current Grounding Line Selection Device

    Overview

    Small current wire selection device is an integral part of the industrial field circuit protection system, the device can accurately determine the location of the fault when the circuit system occurs grounding (arc or metallic) phenomenon, and the information for remote transmission, so as to facilitate the maintenance of the site personnel.

    1.1. Function and characteristics

    The structure of the device adopts modular design, and the main controller adopts 16-bit high performance single chip computer with high speed data acquisition module. Among the modules, CAN communication methods with redundant verification and multi-master transmission are used for data exchange and sharing.The panel uses the display screen and a simple 5-key operation function for man-machine dialogue.

    The system adopts double watchdog mode to detect the operation of the system; wide working input voltage, high current signal measurement accuracy; fault and setting information memory function; real-time data and fault data remote transmission function.
