Introduction

1. Function

Comprehensive Protection Functions Provide full protection for rotating machines: differential protection, overcurrent, earth fault, overvoltage / undervoltage, thermal overload, unbalanced load, abnormal frequency, reverse power, under-excitation protection, motor start-up supervision and trip circuit monitoring.www.plcva.com
Electrical Measurement Real-time measurement of phase current, phase-to-phase / phase-neutral voltage, frequency, active/reactive power, power factor and energy. Supports RTD input for stator and bearing temperature monitoring of generators & large motors.
Local & Remote Control Local manual operation via front HMI buttons; remote control for circuit breakers and disconnectors, with synchronism check and bay-level interlock logic.
Graphical HMI Display (the screen you referred to) The built-in graphic display shows real-time mimic diagram (MIMIC), measured values, alarm messages, fault event records, protection trip logs, parameter settings and self-diagnosis information. Operators can browse data, reset alarms and modify local settings directly on panel.
Condition Monitoring & Self-Supervision Circuit breaker health monitoring, relay internal self-check, fault event recording and disturbance waveform capture for post-fault analysis.
Communication Interface Supports SPA bus, Modbus, LON bus to connect with substation SCADA / DCS systems for data uploading and remote parameter configuration.
Embedded programmable logic Built-in IEC 61131-3 PLC logic for custom bay automation sequence control, reducing auxiliary relay quantity.

2. Applications

Primary use: Protection, measurement, control and supervision for small & medium generators, synchronous motors and large asynchronous motors in power plants and industrial substations.
Typical industries: Hydropower station, diesel power plant, steam power plant, oil & gas, mining, marine & offshore power systems.www.plcva.com
Typical equipment protected: Generator-transformer units, large pump motors, mill motors, crusher motors and other medium-voltage rotating machinery.
Working logic: Current/voltage signals from CT/PT → REM545 terminal acquires and processes data → protection logic runs continuously. If abnormal condition is detected, relay outputs trip signal to cut off equipment; meanwhile the HMI display pops up alarms and fault records for on-site operator checking. Local operators can view mimic status and execute switch operation via front display panel.
