What you can’t see may hurt you
Find out if partial discharge is corroding your HV
Corona from partial discharge emits energy in the
ultraviolet spectrum. The human eye can’t see UV
but the UV-260 Corona Camera can. And it can distinguish background UV from corona even in daylight.
UV radiation emissions will show up superimposed
on the camcorder image so you can precisely locate
the source. Take a snapshot or record a video. A
UV-photon volume counter helps you determine

With the aid of analytics to monitor and analyze condition and performance, transformers diagnosed with
potential failure can be proactively
taken off line. The utility avoids expensive cleanup costs, can store the knowledge gained for “family” failures, and
can obtain potential “grey” spares for
other units—with no loss to the grid.

data for inspection records, as well as
line surveys using handheld devices.

and analysis with the software.
By taking data from assets in more than
40 substations, and monitoring these levels using multiple techniques, engineers
now are warned of any potential failures
in plenty of time in the form of SMS or
email. These are sent in accordance to
alarm levels set for various measurable
parameters within each transformer, such
as Dralim Oil analysis, SF6 gas levels and
DTS (the measurement of temperature
along the length of a transmission line
through use of optical fibers). Users can
view any transformer via a TreeView structure or layout by asset or route. In addition, they can view assets on a geographic
basis through the ordnance survey maps
incorporated into the system.
