Locating a leak in an air pressure
tank
For Leak Detection
Where gas or air leaks produce a turbulence that creates
sonic energy, the ultrasonic detector can detect a 0.002-in.
(0.05-mm) diameter leak at 5 ft (1.5 m) with only 10-psi
pressure. The instrument can also be used to detect leaks
in vacuum systems, and to detect leakage of poisonous,
noxious, explosive or expensive gases in gas pressure
systems.
For Corona Detection
The ultrasonic detector is most useful for locating corona
sources that are exposed directly to the surrounding air,
such as on terminations, high-voltage bus systems,
bushings and transformers. The detector is excellent for
patrolling pole lines and checking all kinds of electrical
equipment for leaky insulators and faulty connections. It is
invaluable in research and development work for locating
points of excessive stress on small electrical components
and assemblies, as well as on very large equipment. The
detector is ideal for finding and cleaning up corona
discharge points on the high-voltage test floor. When used
for locating corona discharge, all suitable safety
precautions must be taken to avoid electric shock.
The detector is excellent for
patrolling pole lines.
