Product Performance

High Precision Measurement Performance: Adopts vacuum-resistant gas extraction membrane technology and built-in temperature conditioning system, moisture measurement accuracy reaches ±2% RH, gas measurement accuracy reaches ±10% of reading, ±25ppm (equivalent Hydrogen), which can accurately collect dissolved gas and moisture content data in transformer oil without distortion or drift, meeting the strict accuracy requirements of power equipment monitoring.

Early Fault Warning Performance: Continuously monitors dissolved gas and moisture content in transformer oil, can detect potential internal faults of transformers in advance, and timely notify operation and maintenance personnel through programmable dry contact relay alarms, minimizing the risk of unplanned outages.

Flexible Adaptability Performance: Supports two measurement type options of composite gas or Hydrogen only, compatible with various transformers with mineral insulating oils or ester based fluids (natural and synthetic), and can be quickly integrated without replacing existing equipment.

Easy Maintenance Performance: Supports online hot swapping, the module can be replaced without stopping the transformer operation, equipped with complete self-diagnostic functions and remote monitoring tools, which can quickly locate fault points, shorten maintenance time and reduce operation and maintenance costs.

Wide Environmental Adaptability Performance: The operating temperature covers -40℃ to +70℃, which can operate stably in extremely cold or high-temperature environments, adapts to various harsh industrial sites, no constant temperature control required, and trouble-free operation all-weather.

Communication Compatibility Performance: Supports RS485 and optional TCP/IP communication protocols, can be seamlessly connected to SCADA or DCS systems, supports remote equipment diagnosis and parameter configuration, ensuring smooth system linkage and centralized management and control.

Expandability Performance: Can connect additional sensors (such as top and bottom oil temperature sensors), compute transformer mathematical models based on IEEE and IEC standards, providing more information on transformer operating status.
