 The
Federal Aviation Administration at Rochester New
York Airport found that they were experiencing
radio frequency interference (RFI) which was causing problems
with air traffic control. To address the issue,
initial inspections were undertaken using
directional radio finding equipment, but it was
not possible to locate the specific defective
elements causing the interference. However, the
source was identified as a 12.47kV distribution
tap to the customer.
A DayCor camera quickly
identified the problem as flat spots on the
aluminium
tie wrap on the 12.47 kV pin insulator. The
resulting arcing had caused the rubber covering
on the wire that was attached to the pin
insulator to erode. The defective hardware was
replaced within 30
minutes, together with
insulators, lighting arrestors and the potheads
on 2 circuits which were 115kV transmission
lines were also cleaned.
The UV Camera quickly
resolved the problem with radio interference
that the control tower were experiencing, saving
time and money. |
