Product Description

The REM543 is a sophisticated relay that offers comprehensive protection for medium-voltage motors, including synchronous and asynchronous machines. It integrates protection, control, and supervision into a single unit.

• Type: Numerical Motor Protection and Control Relay.

• Key Functionality: Motor protection (thermal overload, short-circuit, ground fault, unbalance, etc.), control (breaker/contactor), measurement, and monitoring.

• Design: Modular and compact design for easy integration into switchgear cubicles.

• Communication: Supports various communication protocols for integration into substation automation systems.

• Hardware: Features a powerful processor, high-quality analog inputs, binary inputs/outputs, and a user-friendly Human Machine Interface (HMI).

Product Parameters

The specific parameters depend on the configuration, but here are the typical ranges and key specifications for the REM543 series:

Product Advantages

• Comprehensive Motor Protection: Offers a wide array of protection functions tailored for motors, ensuring maximum operational lifespan and preventing catastrophic failures.

• Integrated Control: Combines protection and control functions, reducing the need for separate devices (e.g., motor starter control and protection are unified).

• High Reliability: Numerical processing ensures high accuracy, repeatability, and fast fault clearance times.

• Advanced Monitoring and Measurement: Provides detailed real-time and historical data on motor performance, current, voltage, power, and energy consumption, aiding in preventative maintenance.

• Flexibility and Customization: Modular design and extensive configuration options allow it to be adapted to various motor types and system requirements.

• Easy Communication: Seamless integration into Substation Automation (SA) systems for remote monitoring, control, and data acquisition.

Precautions

• Personnel Safety: Installation and maintenance must be performed by qualified personnel only, following all local electrical safety regulations (e.g., LOTO procedures).

• CT/VT Circuit Integrity: Ensure the Current Transformer (CT) and Voltage Transformer (VT) secondary circuits are securely grounded and never open-circuited while the primary system is energized. High voltages can occur across open CT terminals.

• Correct Parameter Setting: The relay will only provide effective protection if the settings are calculated and applied correctly based on the motor’s data, CT/VT ratios, and system parameters. Incorrect settings can lead to false trips or failure to protect the equipment.

• Firmware and Configuration Backup: Always back up the relay’s configuration settings and note the firmware version before making changes or updates.

• Supply Voltage: Ensure the auxiliary power supply voltage and polarity (for DC models) are within the specified range of the REM543 unit before connecting power.

Product Applications

The REM543 relay is primarily used in medium-voltage power distribution systems where reliable and sophisticated motor protection and control are essential.

• Industrial Plants: Protection and control of large pump motors, fan motors, compressor motors, and conveyor motors in industries like mining, cement, pulp and paper, and petrochemicals.

• Power Generation: Protection of auxiliary motors in power plants (e.g., boiler feed pumps, circulating water pumps).

• Utilities: Protection of critical motors in water treatment, sewage systems, and main feeders.

• Oil and Gas: Control and protection of large motors driving pipelines and refinery equipment.

• Pumping Stations: Essential for reliable control of critical high-power pumps.
