★ It has multiple alarm functions such as busbar grounding, overvoltage/undervoltage, PT disconnection/undervoltage, and has the function of recording alarm events;

★ Measure three-phase/line voltage and zero sequence voltage;

★ 1 RS-485 communication interface, Modbus RTU communication protocol;

★ 14 channels of switch remote signal input: 2 of them have PT knife switch closing and opening signal access function;

★ 1-channel relay output: used for alarm signal output;

★ Three phase voltage measurement values and SOE event records can be read in real-time through the communication port, and all protection parameters can be set through the display panel;

Scope of application: This single bus PT protection and measurement device is suitable for measuring and protecting single bus PT circuits with voltage levels ranging from 35kV to 6kV.
