Sulfur hexafluoride (SF6) is the preferred insulating and arc-quenching gas for medium and high-voltage electrical equipment around the world. However, SF6 leakage can cause electrical breakdowns and damage the environment. To avoid such incidents, it is important to inspect SF6 equipment regularly. However, there are many factors that can affect SF6 leak detection.
Detecting SF6 Leaks
The power transmission industry relies on sulfur hexafluoride (SF6) to insulate medium- and high-voltage equipment. SF6 is a nontoxic, stable and inert gas that effectively quenches electrical arcs by splitting into six fluorine molecules which capture errant electrons before they can reach the metal surface. But SF6 leaks pose risks for workers and create serious consequences for the environment.
Detecting Sf6 leak camara detector requires a noncontact approach that can be performed without shutting down equipment. Using optical gas imaging Camera Detectors, utility crews can visually pinpoint the location of SF6 leaks and take corrective action, saving money and minimizing emissions of greenhouse gases.
SF6 is colorless and odorless, so it’s difficult to detect with traditional sniffers or soap bubbles. But SF6 leaking from breaker seals, valves, or other components can reduce the insulating performance of the equipment and emit 23,900 times more carbon than CO2. This impacts both the profitability of transmission lines and the safety of employees working on them.
SF6 Leak Camera Detectors
SF6 is a colorless, odorless synthetic gas used to insulate high-voltage electrical switchgear. It is highly effective, cost-efficient and non-flammable, and it significantly reduces the risk of electrical fires. However, a leak in this equipment can cause power disruptions and environmental pollution. Detecting these leaks at an early stage is therefore critical. Several methods can be used to locate SF6 leaks, and the most suitable method depends on a variety of factors. These include temperature, humidity and breaker pressure, as well as the type of insulator and the location of the leak.
Acoustic leak detection is a fast and efficient method for pinpointing the location of SF6 leaks. WEgrid offers a complete range of SF6 leak detectors and accessories for this purpose, including the SF6 Tracker model GA65 and a specialized portable device called SF6 Leakmate. The latter provides a clear LED bar graph display and audible alarm, and it is easy to operate with one hand. It also features battery status and sensor failure indicators and comes with a convenient carrying case.

This top performing infrared Camera Detectors doubles as a portable SF6 gas detector, giving you two critical functions in one tool at a one of a kind price. It allows you to safely conduct infrared and SF6 leak detection at the same time, saving on rental charges and reducing costs of inspections.
This handheld device can accurately detect SF6 leaks and locate them on site. It is ideal for use in the electrical transmission and distribution, manufacturing and industrial processing industries.
The BESANTEK Corporation BST-SF6 SF6 Stable Leak Detector is a compact device that offers professional performance and reliability when testing levels of sulfur hexafluoride (SF6) and other halogenated refrigerants. It has a tricolor visual display and a tactile keypad controls that are easy to use. The instrument automatically compensates all ambient influences like temperature changes or movement of air in the room. It then uses the present concentration as its zero line and begins to look for even higher gas concentrations, indicating them audibly and visually.
SF6 Leak Detector Comparison
Sulfur hexafluoride is an excellent insulation and coolant for electrical switchgear, but it’s also the most potent greenhouse gas. Therefore, it’s critical to keep SF6 leak rates low for safety and environmental responsibility reasons.
Acoustic leak detection is a new method that provides efficiency and sensitivity with minimal impact on equipment or breaker performance. This technology utilizes acoustic sensors to measure the ultrasonic frequencies produced by escaping gas under pressure. The detector pinpoints leak locations and alerts the operator, so repairs can be made quickly to reduce downtime.
This elite handheld SF6 leak detector from DILO is easy to use and has multiple sensitivity levels for precise tracing of small leaks. Its quick response time and easy-to-read LED display eliminate the need for a laptop or additional meter, which improves worker safety. With a 10-year sensor lifetime, this SF6 leak detection instrument is ideal for substations and other power utility equipment. This acoustic device has no cross sensitivity to other gases and does not depend on temperature or moisture, making it a reliable choice for your next SF6 inspection.
More Words
SF6 is an insulating gas that powers electrical equipment but also has 23,900 times the global warming potential of CO2. Finding leaks is crucial to ensuring power continuity and protecting the environment. Using a thermographic Camera Detectors allows for non-contact detection of the gases from safe distances and significantly reduces inspection time while equipment remains in service. It’s easy to use and provides clear, concise results.
