sf6 o2 detection systems for HV MV

sf6 o2 detection systems for HV MV

Arc fault detection is critical to protecting all types of switchgear, ranging from LV,MV,HV equipment. When arc faults occur a flash of light is emitted. This includes all IR and visible radiation spectra, Light reaches each point around the fault instantaneously. To take advantage of light's speed, Light Arc Detectors (LAD's)
