Product Performance

Multi-Gas High-Precision Detection: Simultaneously monitors 7 types of characteristic gases dissolved in transformer oil. The detection accuracy of core fault gases (H₂, C₂H₂) reaches ±5% reading, which can accurately capture the gas concentration changes of early internal equipment faults and avoid missed or misjudgments.
Real-Time Monitoring and Rapid Alarm: The shortest detection cycle can be set to 15 minutes, with response time ≤30 minutes. When the gas concentration exceeds the preset threshold, it immediately triggers local sound-light alarm (red LED + buzzer) and remote system alarm (SMS/platform notification), gaining disposal time for operation and maintenance.
Wide Environmental Adaptability: The operating temperature range of -30°C to +60°C covers high-latitude cold regions and high-temperature outdoor environments. The IP54 protection class can resist rain, snow and dust, and can be installed outdoors without additional protective boxes.
Strong EMC Immunity: The main unit adopts an electromagnetic shielding shell, and the sampling line is equipped with surge protection (10kV/5kA). The data transmission bit error rate is ≤10⁻⁹ in the strong electromagnetic environment of the substation, ensuring stable and reliable monitoring data.
Intelligent Fault Diagnosis: Built-in GE’s patented “DGA Trend Analysis Algorithm”, which can automatically identify typical fault types such as partial discharge, low-temperature overheating (150-300°C) and high-temperature overheating (>300°C), generate monthly/quarterly fault trend reports, and assist operation and maintenance personnel in formulating maintenance plans.
