The DayCorII Bispectral Corona Camera was developed by
Ofil , in cooperation with EPRI (Electrical Power
Research Institute) in the US, to detect and locate
corona, arcing and partial discharge on high voltage
lines. Supplied in two forms (fixed mounted or full
portable) these units superimpose UV and visual
wavelengths images to show corona problems typically
seen in high voltage distribution lines and substations.
The camera consists of two imaging channels: a UV
sensitive channel to image the corona, and a visible
channel to image the surrounding scene (insulators,
spacers, cables etc) The two images are overlaid to
produce one image with both the corona and the
surrounding scene. The camera thus detects the corona
and pinpoints the location of the corona source. This
enables the operator to determine the condition of the
component from a safe distance and determine whether any
corrective action is required.
The DayCor uses a high quality LCD display for outside
conditions so that the operator can view corona problems
live in the field. The images are easy to interpret due
to the simplicity of operation and are often compared to
a camcorder in usability. The direct access buttons mean
the setting up of the unit is quick and easy compared to
complicated equipment that uses extended menu systems.
The recorded information can be downloaded into a full
software package for post analysis and quick reports.
This will allow the user to design routes for his next
inspection and when to schedule them based on
criticality.
A complete range of lenses, software and accessories are
available to customise the DayCor to specific
applications.
Consilla Limited are pleased to offer no obligation
demonstrations at your premises and recommend a suitable
configuration.
