Feb 20, 2021 · To avoid this, always check your breakers often. You can check that via the pointer of the gas gauge. If the gauge shows a decrease in gas pressure, subject it to a gas leakage test. Gas leakage tests require soap water, or an Sulfr hexafluoride detector. If there is a leakage, consult an engineer for rectification. You can also fill up the circuit breaker with the new Sulfr hexafluoride gas to balance the pressure loss. Thanks for reading the article.
