For quick detection and quantification of small SF6 leaks, the cordless, battery-operated DILO 3-033-R200 SF6-LeakSpyprecisely measures SF6 concentration by means of a non-dispersive infrared sensor (NDIR sensor) and indicates the value on a graphic display in ppmv.
Sulfur-hexafluoride (SF6) is used as a dielectric in high power gas insulated equipment such as breakers, switches, transformers and transmission lines, and is normally a very stable, non-reactive gas, even in the presence of high energy discharge.
As part of preventative maintanence in most substations, measurement of humidity in SF6 gas should be completed. If the humidity content is within manufacturers’ specified limits, then the possibility of HF and SO2 creation is very low. If the humidity level is extreme, then those by-products will be created in high enough concentrations that corrosion will occur in the insulators, resulting in undesirable short-circuiting within the equipment.
With an integrated thermostat that prevents the gas bottle from being overheated, installation of the DILO SF6 Cylinder Heating Blanket is easy, just wrap the blanket around the lower portion of the cylinder and secure it via two Velcro® straps.
The DILO 3-038R-R303 Zero Emission SF6 Analyzer with gas return system is a compact, easy to use device that allows for the determination of up to six parameters with only one measurement, and noSF6 gas is released into the atmosphere.
With the ability to test SF6 purity (vol %), moisture content, and byproducts (SO2), the DILO 3-038R-R303 Zero Emission SF6 Analyzer features an onboard storage vessel and compressor where the test gas is captured and pumped back into the switchgear.
An SF6 electrical circuit breaker operates with SF6 or Sulphur Hexafluoride being carried on its contacts. It works by breaking off the power when the electricity supply exceeds the allowed voltage in order to prevent circuit overload.
