Dual bus PT parallel protection measurement and control device/PDM-850C-U2

★ It has multiple alarm functions such as bus grounding for I/II bus, PT disconnection/voltage loss, overvoltage/undervoltage protection, and has the function of recording alarm events;

Measure the three-phase/line voltage and zero sequence voltage of two sections of busbars respectively;

★ Equipped with PT automatic parallel function, it can prevent reverse power transmission of bus PT and improve the operating efficiency and safety of bus PT;

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

★ 14 channels of switch remote signal input: Among them, 3 channels have the functions of 1 # PT knife switch closing position/2 # PT knife switch closing position/allowing PT parallel signal access;

★ 2-channel relay output: used for alarm signal output and PT parallel 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 dual bus PT parallel protection measurement and control device is suitable for measuring, protecting, and paralleling dual bus PT circuits with voltage levels ranging from 35kV to 6kV.
