The stable operation of power systems directly impacts industrial production and public welfare. Prolonged high-load operation of electrical equipment, influenced by factors such as current load, environmental corrosion, and component aging, often leads to failures like loose connections, damaged insulation layers, and internal short circuits. These issues frequently manifest as abnormal heat buildup, which is difficult to detect with the naked eye. Thermal imaging cameras, as efficient, non-contact, and pollution-free inspection tools, have become a powerful safeguard for detecting faults in electrical equipment.

Technical Principles
All objects above absolute zero (-237.15°C) emit infrared thermal radiation outward. While invisible to the human eye, thermal imaging cameras reveal this radiation by detecting the emitted waves, converting them into electrical signals, and processing them into visible thermal images. The color distribution within these images provides an intuitive representation of surface temperature variations across objects.

The MV-GF120, independently developed by MindVision, is an industrial far-infrared thermal imager capable of measuring surface temperatures and displaying real-time thermal images.

Product Advantages
Precise temperature measurement and high sensitivity
Emission factor settings, distance correction, and humidity correction are available, with emission parameters tailored to the materials of different electrical equipment to ensure accurate and reliable temperature measurement data. Utilising an infrared detector with high thermal sensitivity (≤55mK), it can distinguish minute temperature differences of ±1℃, identifying thermal anomalies during the early stages of electrical equipment faults.
Detail Capture and Dynamic Monitoring
400×300 resolution clearly displays surface temperature distribution details on equipment, preventing missed hazards due to insufficient resolution. Combined with a 50Hz frame rate, it rapidly records temperature spikes during electrical faults, providing a complete dynamic temperature data chain for fault root cause analysis.
Ultra-fast response and stable transmission
The device features a thermal response time of <15ms, enabling rapid capture of temperature changes and real-time detection of sudden overheating events. Through its RJ45 Gigabit Ethernet interface, it ensures stable transmission over distances up to 100 meters, guaranteeing lossless delivery of massive thermal imaging data collected at the front end to the server without frame loss. Furthermore, the device supports multi-camera collaborative networking, effortlessly achieving comprehensive, seamless detection coverage in large-scale substations and similar scenarios.
Intelligent Analysis and Early Warning Function
Supports user-defined areas of interest for precise monitoring of critical equipment. Additionally, the device supports high/low temperature alarms and user-defined temperature range alerts, with alarm parameters configurable based on the safety thresholds of different equipment materials.
Whether identifying potential hazards during routine inspections or tracking data for sudden failures, the MV-GF120 delivers stable, efficient technical support, enabling power detection to transition from “passive response” to “proactive early warning.”
Mount thermal imaging cameras in critical equipment zones within substations to capture infrared thermal images of electrical equipment. These thermal images and temperature measurement data are then transmitted in real time via Gigabit Ethernet to the backend monitoring center. This process enables non-contact temperature monitoring and fault diagnosis of electrical equipment without requiring personnel to approach high-voltage equipment at close range.
