Title: Air content determination for gas filled installation - involves measurement of speed of ultrasonic signal by timing it over given distance
Inventor: HOLLMANN FRITZ
IPC: H02B13/055
Filed: 1978-04-29
Abstract: A gas filled electrical installation e.g. a transformer or a circuit breaker uses a gas such as SF6. In SF6 insulated installations a small leakage of air will degrade the insulation quality. The gas can be tested for purity without direct sampling by using an ultrasonic system. The system is deisgned to measure the time required for an ultrasonic signal to traverse a given path through part of the installation. The measurement method rests upon the fact that the speed of sound through a gas is affected by its density and composition. Leakage of air into SF6 is thus discernable. Measurements are best made at predetermined calibrated points on the installation.
