Description. 973-Sulfr hexafluoride gas analyzer used for simultaneous measurement of humidity, SF 6 purity and SO 2 concentration. Pure SF 6 is the standard filling within GIS, but over time gas compartments become contaminated with water vapor (H 2 O) through permeation and by desorption from internal materials. Whilst water vapor and SF 6 do not normally react with each other, in the presence of a high-energy discharge, hydrogen and oxygen disassociated from water vapor will react with the sulfur and

Recommended circuit breaker tests - Electrical test equipment

It is important that the moisture content inside an insulating gas breaker is kept to a minimum as it can cause corrosion and flashovers inside the breaker. When there is arcing (i.e., faults or normal interruptions) inside of the circuit breaker, the insulating gas combines with water to produce corrosive by-products. Air pressure test; applicable for air-blast breakers. Air pressure level, pressure drop rate and air flow are measured during various operations.

Frequently asked high voltage circuit breaker testing

Most manufacturers don’t recommend Power Factor testing gaz sf6 dead tank circuit breakers. To check the quality of the insulating gas gas i.e. the insulation of the CB, it is recommended to perform a moisture and purity test on the sf 6 gas. There have been some reports that you can determine some issues within the CB contacts with a Power Factor test, so several utilities still promote and perform these tests on sf 6 circuit breakers.
