The TOLMS, Transformer Oil Level
Monitoring System, from Redragon
Oil & Gas Systems
International Inc. is a system
that can be retro-fitted to
existing degasifiers to provide a
convenient means of processing oil
on energised transformers. The
system is available as a
factory-fitted option on all
Redragon TORS and HVD series oil
treatment systems. As a retro-fit
it is complete with its own
electrical enclosure containing
all electrical components and
Allen-Bradley PLC.
The TOLMS allows the transformer
to be conveniently topped-up with
extra oil and allows the oil hoses
to be filed with oil all while
connected to the transformer – no
change of hoses or moving
oil-filled hoses is required.
Oil level monitoring is achieved
via a pressure transducer that is
connected to the control panel. A
graduated audio-visual alarm
system is employed. In the event
of an excessive oil level decrease
in the transformer, caused by a
hose rupture for example, the
TOLMS will automatically isolate
the transformer drain valve
prevent catastrophic loss and
transformer damage.
