12.0User set-up

This gives access to a number of parameters which determine the behaviour of the instrument. They are described as follows and all are selected using the up/down arrows and changed using the -/+ buttons.

12.1Peakhold (gauge). This due to the short recovery time after detecting a leak, this function is helpful. The peak value will be held on the handgun display for the time you select. In position OFF, no peak hold occurs.

12.2Peakhold (screen) on the touch-screen, two leak rate displays are visible: the main display in big digits, and the auxiliary display below it. One of them always shows the ‘live’ reading, while the other holds a peak value (if selected). This is factory pre set to AUX DISPLAY.

In this position (AUX DISP) the big display shows the live reading, while the auxiliary display holds the peak. If set to MAIN DISPLAY, the peak hold is held on the big display, while the auxiliary display shows the live reading.

The peak hold seen on the console display represents the value that is stored in memory when the STORE key is pressed. Pressing either the STORE or CLEAR buttons resets this.

12.3Display units

The touch-screen display and alarm level entries, as well as reference leak values, will operate in the units you select.

Use the +/- buttons to change between E-6 ml/sec, E-7 ml/sec, gm/yr and ppm.

For gm/yr and ppm measurements, all the above parameters are held separately and do not need to be re-enteredwhen changing between leak rate and concentration modes. There is also a separate calibration factor for each mode.

Gm/yr (weight loss) and ppm (concentration) measurement should not be used for leak detection. Leaks are measured in volume loss/time (ml/sec). .ppm mode demands a higher sensitivity, than leak rate mode. When measuring low ppm concentrations the display responds considerably slower. Response time depends on the actual concentration and, at very low levels, may exceed 10 seconds.

In the present software version, the ppm mode is still in an experimental state. Therefore all information is approximate. For precise ppm measurement it is recommended that calibration is made to a 10ppm SF6 in air source. For more information please contact ISL.

Desens Factors. Allow large leaks or large concentrations to be displayed.

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.
