On-Site SF6 Transmitter unit - schallmarkus.de SF6 Transmitter unit. TGas-1031 On-line Gas Transmitter - Globeinstrument on-line gas transmitter which adopts high performance sensor unit can continuously measure the concentration of gas on site and convert the concentration signal into digital or analog signal output(4-20mA analog signal,RS485 communication signal and switch quantity alarm signal to transmit remotely and drive)..
SF6 gas - WIKA plant safety of SF 6 gas-insulated switchgear is reduced significantly through low concentrations of decomposition products. These decomposition products arise during operation through arcing in moist or impure SF 6 gas. In order to detect even the smallest leakages or to warn ahead of gas emissions, we have a range of high-quality gas detectors and emission monitors.

Improving the accuracy of SF6 leakage detection for high ... though average leakage rates of SF6 in high voltage equipment are very low, there is no guarantee for a 100% leakage-free system, especially when considering the generally long lifespan of high-voltage equipment. Taking in view the rather strict maximum allowed leakage rate of SF6 per year, regulated by international standards, these facilities should be equipped with suitable monitoring ...Cited by: 13
