FLAIR 23DM Voltage Detection Relay (Part No. EMS58355)

FLAIR 23DM Voltage Detection Relay (Part No. EMS58355)Product OverviewFLAIR 23DM is an intelligent voltage monitoring device developed by Schneider Electric for medium voltage gas insulated ring main units (RMU, model SM6/RM6). It integrates three-phase voltage measurement, grid fault alarm, live-line detection and remote Modbus communication. It can be matched with VPIS-V0 voltage presence indicators and EMS58423 connecting cables as a complete set, widely used in distribution switching stations and outdoor RMU cabinets.Core Functions

Real-time monitoring of L1/L2/L3 three-phase voltage, accurately detecting live state, voltage loss and phase failure.

Medium voltage grid fault channel indication: automatically capture short-circuit, earth fault and phase loss faults, display fault phase and fault code on local LCD screen.

Relay output for voltage presence / absence logic, to trigger local indicator lights or remote alarm equipment.

Built-in Modbus RTU communication port, supporting connection to SCADA and distribution automation systems for remote data upload and unattended monitoring.

Key Advantages

Integrated LCD display for local real-time voltage reading and fault query, easy on-site commissioning.

DIN rail mounting design, fully compatible with Schneider medium voltage switchgear cubicles.

Matched with original VPIS-V0 live voltage indicator, the whole system complies with IEC 62271-206 standard.

Industrial wide-temperature hardware, resistant to high temperature, humidity and strong electromagnetic interference inside switch cabinets.

Standard Modbus protocol compatible with most distribution monitoring platforms, convenient for intelligent power grid upgrade.

Application Scope10kV ~ 36kV medium voltage ring main units, gas insulated switchgear, outdoor distribution cabinets, commercial & residential power distribution stations.
