4.0SYSTEM PROPERTIES: Introduction:

GAS-CHECK SF6 is a portable, mains-independent instrument for leak detection and leak measurement of SF6 gas. Although designed for SF6, other gases with a high affinity for electrons, such as refrigerant R12 may also be detected.

Although designed for operation without training, we recommend that this manual be read before use. This manual and the instrument have been designed to be understood by users whose first language is not English. Please advise us of any changes, which will make this easier.

Two modes of operation are available, volume loss/time cc/sec (leak-detection) and (ppm) concentration of SF6 in air.

All controls and displays required for detection are found in the hand unit. Accurate and clear measurement is achieved from the console touch screen display.

Measurements can be stored in the instrument and later transferred to a printer or computer. A battery-powered printer is available. Results may also be downloaded to a computer via the RS2323 link.

The only item, which needs to be replaced in normal use, is the ‘Smart Sensor’ probe. Smart Sensors contain a microchip programmed with specific sensor information. At Switch ON, the console automatically reads sensor information.

Smart Sensors are not radioactive and contain nothing harmful. Life is approximately 200hours. Sensors are changed by switching OFF the instrument and plugging in a replacement. Three (3) are supplied and available as exchange items.

The operation of the instrument and sensor require permanent and precise control by software. Any faults give immediate error messages, which are then displayed on the touch screen. This in conjunction with the sample flow monitoring function, ensures the instrument reliably determines and displays all fault conditions.

All vital user parameters are password protected against unauthorised entry.

Access to the touch-screen is required for set-up only. If used outside or in difficult conditions the transparent cover over touch-screen can be left locked.

4.1CONSOLE CONTROLS:

1 Touch-screen for numeric leak rate display and parameter entry.

Two red on/off buttons located at the front and right side panel. Both are lit when the instrument is on. White light combines mains supply and battery charge control. This flashes while on charge and is permanently on when the battery is full.

A Key allows the transparent front cover to be locked during use.

SF6 specifications

Innovation technology in the realm of electrical applications has increasingly turned its focus towards SF6, or sulfur hexafluoride. This gas is recognized for its excellent insulating properties and is widely utilized in high voltage equipment. SF6 is colorless, odorless, and non-toxic, making it a preferred choice for many industries, particularly in electrical utilities and power generation.

One of the main features of SF6 technology is its superior dielectric strength. The gas can prevent electrical discharges even in high voltage environments, which minimizes the risk of electrical failures and enhances the safety of electrical equipment. Furthermore, the thermal stability of SF6 allows it to withstand significant temperature variations, making it highly effective in various environmental conditions.

Another notable characteristic is its ability to quench electrical arcs. SF6 has a high electron affinity, meaning it can effectively absorb free electrons present during arcing, thereby extinguishing the discharge. This feature is crucial for circuit breakers and switchgear, ensuring reliable operation and protection against faults.

In addition to its insulating capabilities, SF6 technology supports a range of innovations in smart grid applications. The gas is compatible with advanced monitoring systems that facilitate real-time assessments of electrical equipment’s health and performance. These monitoring systems can detect potential issues before they escalate, promoting preventive maintenance and reducing downtime.

However, despite these advantages, the environmental impact of SF6 has raised concerns. As a potent greenhouse gas with a global warming potential significantly higher than CO2, industries are exploring alternatives and seeking ways to mitigate SF6 emissions. Innovations such as gas mixtures and the development of alternative insulating technologies are underway, aiming to address these challenges while maintaining reliability and efficiency.

Furthermore, ongoing research continues to improve the lifecycle management of SF6, encompassing better handling, recycling technologies, and effective disposal methods. Transitioning towards a circular economy in the use of SF6 presents an exciting frontier in electrical technology, marrying the benefits of reliable insulation with unwavering commitment to environmental stewardship.

In conclusion, innovation technology in SF6 embodies a blend of superior electrical performance and an urgent need for sustainable practices, marking a pivotal point in the evolution of electrical engineering and power management systems. As industries navigate the balance between performance and environmental responsibility, SF6 remains at the forefront of technological advancements in high voltage applications.
