7.3LOW FLOW ERROR:

The flow through the sensor is controlled by the vacuum pump. The level of vacuum required to maintain the required flow can be seen in the lower LH screen. Should the sample intake of the sensor be partially or totally blocked, the instrument will first try to compensate by increasing the vacuum. If unsuccessful, an error is reported.

You have the choice to confirm one of the following instructions: TRY TO CONTINUE Instrument will try to resume normal operation. This is useful if the blockage can be overcome with a higher vacuum. The LOW FLOW ERROR may also occur if the sensor cap was changed for the capillary probe, this needs higher vacuum to maintain the sample flow. BEFORE changing probes and sensors ALWAYS switch OFF.

The ideal vacuum levels for a clean filter are: -100 to -300mb.

To fit the capillary probe, FIRST switch the instrument off. This allows the new flow levels to be automatically compensated.

7.4FLARE STALL:

This relates to sensor condition. Two reasons are possible for this.

1Very high concentration of SF6 many times above the measuring range.

2High vacuum in the probe caused by a partially blocked or aged sensor.

The instrument will attempt to compensate for these until a level is reached where the detector will stall. At this point the instrument must be switched OFF and the sensor changed.

7.5LOW BATTERY VOLTAGE:

If the battery becomes discharged, the operator is warned of the pending shut down.

If main’s power cannot be made available, operation can be resumed for a short time, but the instrument may now shut down at any time without further warning.

7.5SWITCHING OFF:

During system shutdown, the processor updates the memory, releases vacuum, and turns OFF the touch-screen. To shutdown, press one of the on/off keys for several seconds. A time bar on the screen visualises the hold time.

When the time bar is complete, the button should be released. If it was held down longer, the shutdown sequence will not finish properly.

8.0SWITCHING OFF IN CASE OF FAULT:

Normally, shutdown is controlled as described above. Should this process be changed by a serious failure, the instrument can still be switched off under hardware control. This activates whenever one of the on/off keys is continuously held down for approx. 10 seconds.

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.
