  • Leak testing note #01-01 High Voltage switchgear

    Several tracer gas leak test methods, at both the subassembly and final assembly level, can be employed for leak testing of high voltage switchgear. Consideration should be given to the methods’ ability to both locate the leak and certify the global leak tightness of the system. Both SF6 and helium can be considered for tracer gas.

  • SF6 leak detection of high-voltage installations using TEA

    Apr 01, 2010SF 6 is known as an effective insulator due to its high dielectric strength. Because of this property, it is vastly used in the sealed high-voltage (HV) installations and compact electrical distribution sites. Since then, sensing of SF 6 leakage takes significant environmental and economical advantages due to its high greenhouse effect. Here, we have quantitatively shown that our homemadeCited by: 28

    The indoor space in which the SF6 high-voltage equipment is installed is generally tightly sealed. Once the SF6 gas leaks, the air circulation is extremely slow, and the toxic decomposition products are deposited indoors, which is difficult to discharge, which poses a great danger to the workers entering the SF6 switch room.
