Description

Ensuring the uninterrupted operation of distribution grids is essential for maintaining industrial assets and infrastructure. Energy companies face immense pressure from aging infrastructure and increasing demand for affordable energy, which strain substations and grids, heightening the risk of costly and disruptive brownouts and blackouts. Effective monitoring solutions for retrofit installations are necessary to prevent utility failures, enhance capacity, maintain reliability, and manage costs.

Understanding how heat is distributed within substation components is critical. Electrical resistance causes these components to deteriorate over time, sometimes rapidly. When electrical current flows through these degraded parts, it generates heat. Thermal imaging technology can visualize these issues, enabling early detection of potential failures. However, utilities increasingly find that handheld infrared scanning is inadequate for continuously monitoring critical substation components. Deploying thermographers in every substation, especially during peak loads when issues are most likely to surface, is impractical.

Thermal imaging cameras, as part of a preventive maintenance strategy, can detect problems in electrical utilities before they escalate, thereby controlling costs. Failures in critical substations, such as overheating transformers, can be catastrophic. Fixed-install infrared cameras provide round-the-clock monitoring of crucial components, identifying signs of wear or potential failure through temperature changes. Previously, the widespread use of infrared cameras was hindered by high costs.

Another application is early fire detection in outdoor environments such as paper mills, sawmills, biomass power plants, scrap metal facilities, and waste recycling plants, where the risk of fire is particularly high. Annual financial losses from fires in these settings are significant due to inadequate early detection systems. Infrared cameras are highly effective for monitoring vast areas, providing early warnings that are essential for implementing fire emergency plans.

Industrial settings often require equipment monitoring and early fire detection in extreme temperatures. For example, conveyor systems transporting coal or wood chips in cold climates face the risk of overheating bearings, which can jeopardize operations and increase fire hazards. In wood chip processing, friction can generate sparks, igniting fires in wood pulp operations. Additionally, large piles of decomposing mulch or biomass can spontaneously combust, posing severe risks to nearby factories or residential areas.

The PI 640i CM package meets the need for continuous monitoring in these demanding environments. This package includes all necessary components for effective equipment and fire hazard monitoring, providing early alarms when overheating or fire risks are detected. The package comprises an infrared camera, an outdoor enclosure with a heater and fan, a front window air purge, a high-definition video camera, and a USB Gigabit Server for long-distance video transmission.

The PI 640i CM Package features a PI 640i infrared imager, a visible camera, and the USB Server HT, all pre-assembled in an outdoor housing with a wall mount. The redesigned Optris housing, equipped with a built-in heater and fan, allows operation at temperatures ranging from -40 °C to 50 °C (-40 °F to 122 °F) without compromising measurement accuracy.

With a frame rate of 32 Hz and a resolution of 640 x 480 pixels, the PI 640i can detect even the smallest temperature differences, thanks to its 40 mK thermal resolution. The HD VIS camera, offering a resolution of 1280 x 720 pixels, a 30 Hz frame rate, and a 65 field of view, enhances combined thermal and visual condition monitoring and early fire detection.
The PI 640i CM Package delivers substantial savings compared to custom installations by integrating these elements into a single, cost-effective package. It enhances fire safety by enabling the monitoring of more areas from multiple locations. Its affordability supports comprehensive area coverage and more effective early fire detection solutions.

The PI 640i CM Package’s advanced detection strategy pinpoints hot spots using every pixel in the high-resolution 640 x 480 infrared camera. The PI 640i’s high-speed processors continuously scan the field of view for temperatures exceeding set thresholds. The infrared camera’s process interface port can send alarm signals to external control devices or sprinkler systems. Additional modules can be added to set fire alarm temperatures across different camera views, further enhancing the system’s ability to detect and respond to potential fire hazards.

This system also supports transmitting high-resolution thermal and video images to a control room PC equipped with PIX Connect Software. The software can display multiple images from various locations, enabling real-time thermal video analysis to identify false positives, such as exhaust pipes or solar reflections, preventing unnecessary fire control activations or evacuations.

Engineered and manufactured in Germany, the PI 640i CM Package is a comprehensive and affordable early fire detection solution. Global engineering support ensures effective installation and operation in various industrial settings. The PI 640i CM Package’s reliability, affordability, and advanced features make it an ideal choice for utilities seeking to enhance their continuous long-term monitoring capabilities.shio
