The Enervac GRU-4 SF6 Gas Recovery Unit incorporates a new and improved high pressure, totally oil-less compressor capable of 1000 psig (7 MPag) of pressure. This new technology allows for liquefaction of SF6 gas even in the warmer climates typical of the southern United States.
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.
