The SF6 Multi Analyser is a user and maintenance-friendly device which guarantees high measuring accuracy. First of all, the gas is checked for decompositions products. If critical SO2 values are determined the measurement can be interrupted. In case of contaminated SF6 the complete measuring gas can be recovered from the internal vessel.

Feb 01, 2014Reaching the envisaged accuracies is a challenge for commercial density sensors which are designed for tracking SF 6 densities of 40 kg m −3 and higher at much lower absolute accuracies than required here. For that reason, the density sensors needed to be calibrated in-house to make them suitable for pTρ measurements on SF 6-N 2 mixtures.

SF6 6100 Pump Back Gas Analyser The Rapidox SF6 6100 Pump Back is a fully-automatic zero-emissions SF6 gas analyser, designed for controlling and monitoring the quality and purity of gas used in high voltage switchgear, circuit breakers and transformers. Exceptional accuracy and stability are provided when measuring the purity of SF6 gas, through specially selected sensors.

If a leak, a leaky spot or an indefinable problem occurs somewhere things quickly heat up. You then need someone with a cool head to tackle locating the problem. However, the best thing is to make sure that it does not get that far in the first place: for example through professional commissioning, optimum setting, regular maintenance, random leak detection and endoscopic measurement.

The gas density sensor is self-calibrating and specifically designed to operate as a sulfur hexafluoride (SF6) monitor and control device in gas insulated high-voltage switchgears (GIS), but can

Electronic SF6 gas density monitoring with patented quartz tuning fork The Gas Density Sensor uses a quarz tuning fork to sense gas density directly – a unique technology patented by Trafag. With the delivery of continuous output signals (analogue or digital) from this electronically operating sensor, Trafag opens new paths for the energy

unit and its sensors and also increase the field wiring effort. Instead, for these breaker types, each pole is monitored by a separate 2-slot unit. The 2-slot units are connected to sensors installed on the same pole and communicate their data via an RS485 bus. A forth unit residing in the breaker main cabinet acts as a common data access point.

Sulfur hexafluoride is a sulfur coordination entity consisting of six fluorine atoms attached to a central sulfur atom. It is the most potent greenhouse gas currently known, with a global warming potential of 23,900 times that of CO2 over a 100 year period (SF6 has an estimated lifetime in the atmosphere of between 800 and 3,000 years).

In the EU-28, the SF6 amount in switchgear is unclear. In this paper, we estimated the SF6 amount to be between 10,800 and 24,700 t (with a mode at 12,700 t) in 2017, resulting in 68 to 140 t of annual emissions from operational leakage only, corresponding to 1.6 to 3.3 Mt of CO2-eq.

Filling and handling equipment for SF6 gas are the central tools for the maintenance of gas-insulated equipment. For both installation and maintenance, WIKA supplies the complete product spectrum of efficient service equipment, starting from simple filling carts up to complex, fully automated all-in
