iPec PD-SG Series Quick Start Manual

Parabolic Reflector is an ultrasonic sensor for use when detecting partial discharge
activity on exposed insulating surfaces. The reflector increases the sensitivity of the
sensor allowing detection to be effective at up to 25m. It is commonly used in outdoor
switchyards to detect surface discharge on string and post insulators, sealing ends and
other exposed equipment.

Assembly and start-up

•
Remove the protective plastic film from the reflector completely.
•
Put the reflector carriage on the main beam and turn the handle hand-tight.
•
While assembling and disassembling, touch only the reflector carriage in order to
avoid damage.
•
Connect the Parabolic Reflector cable to the PD-SGS.
•
Turn on the red dot sight. Choose one of the predefined light intensities for your
specific lighting conditions

Use of Parabolic Reflector

With the Parabolic Reflector connected to the PD-SGS, the reflector should be pointed
at the HV equipment being inspected.
Look through the view finder with both eyes open and line up the red dot visible
through the view finder with the centre of the inspection area.
The PD-SGS instrument should be operated in AE Mode (See PD-SGS Operation Manual)
and it will register a dB reading on the user display. It will also generate an audible
output according to the level of activity detected.
It is recommended that when using the Parabolic Reflector out of doors, the head
phones are worn in order to minimise interference from outside noise sources.
Owing to the nature of acoustic PD detection and natural variations caused by
environmental conditions, it is recommended that PD levels identified are appraised
according to their relative values when compared with other similar plant and not in
absolute terms.

Maintenance and Servicing

•
If necessary, clean the equipment with a damp cloth. Do not use solvents
as this may damage the surface.
•
After use, the equipment should be disassembled and stowed in the
carrying case.
•
Replace low batteries immediately with a new cell of the type CR2032
3V. The battery box is situated on the lower surface of the red dot sight.
