COMEM BR80 EN 1M/S BUCHHOLZ RELAY MONITOR GAS & OIL FLOW SMART TRANSFORMER 92477

The COMEM BR80 EN 1MS is an advanced, microprocessor-based monitoring system designed specifically for Buchholz relays on power transformers. It transforms the traditional, mechanically-actuated Buchholz relay into a “Smart” diagnostic tool, providing precise, real-time monitoring of gas accumulation and oil flow surges. This device is a critical component for the early detection of internal transformer faults, enabling predictive maintenance and preventing catastrophic failures.

Key Features & Benefits

• Smart Monitoring & Early Fault Detection: Continuously monitors the gas accumulation chamber and flow vane of the Buchholz relay. Provides early warning of incipient faults (like slow-forming insulation breakdown) and rapid detection of major faults (like arcings), allowing for timely intervention.

• Microprocessor-Based Intelligence: Features advanced digital processing for accurate and reliable measurements. It distinguishes between normal operational fluctuations and genuine fault conditions, minimizing false alarms.

• Dual-Channel Monitoring:

  • Gas Accumulation Monitoring: Precisely measures the volume of gas collected in the Buchholz relay, a key indicator of internal overheating or partial discharge.

  • Oil Flow Surge Monitoring: Detects sudden surges in oil flow caused by internal pressure waves from severe faults.

• Programmable Setpoints & Alarms: User-configurable thresholds for both gas volume and oil flow. Allows for customized warning and trip alarms to match the specific protection philosophy of your transformer.

• Robust Enclosure & Certification: Housed in a 1MS (Stainless Steel) enclosure, it is built to withstand harsh substation environments. It complies with relevant international standards (e.g., IEC) for electromagnetic compatibility and environmental resilience.

• Clear Visual Indication & Remote Communication: Features local LED indicators for status and alarm conditions. Equipped with communication ports (e.g., RS485) supporting protocols like Modbus RTU, enabling seamless integration into SCADA, DCS, or transformer monitoring systems for remote data acquisition and control.
