In Japan, electric power utilities periodically inspect the
suspension insulator units on transmission lines. Line workers
check the allotted voltage or the insulation resistance of
insulator units using a hot stick, an automated faulty insulator
detector, or other detectors. For safety and efficiency a
remote sensing system is desirable. This type of system is
indispensable for UHV transmission lines, since higher
electric fields prohibit workers from being outside the tower
frame under energized conditions.
Most of the faulty suspension insulator units removed from
transmission lines have cracks in the porcelain. The vibration
characteristics of a cracked insulator unit differ from those of
a sound unit. We have developed a prototype system, which
can detect a cracked insulator unit at a distance up to 50m
apart from the insulator. The system consists of an acoustic
radiator, a laser doppler vibrometer, and a control unit.
