An experiment was carried out to simulate an SF6 gas leak by transferring SF6 gas from one gas bottle to another. The objective of this experiment was to ascertain whether there were any disparities in how each type of transducer tracked an SF6 gas leak. A quartz oscillating density transducer, a pressure and temperature - calculated density transducer, a pressure transducer, and two temperature sensors were used to monitor the controlled leak. The transfer of SF6 gas between the bottles was regulated by a needle valve to minimize the SF6 leak rate as much as was practically possible.
The experiment was conducted indoors within a non - climate - controlled environment, where there was no direct sunlight influencing the transducer measurements. However, during the experiment, the ambient temperature fluctuated between 17 and 29°C. The results of this experiment indicate that there is no substantial difference among the types of transducers that can be retrofitted to a circuit breaker for SF6 density monitoring.
