The Kelman DGA **0 TAPTRANS is the
next generation *-gas on-line transformer multi gas DGA
(Diagnostic Gas Analyzer) monitor. Built from the DGA **0
platform, the TAPTRANS extends the capability beyond measuring a
single transformer main oil tank.
Knowledge of the condition of
transformers is essential for all electrical networks and on-line
monitoring of transformers is an increasingly vital component of
successful asset management programs. The comprehensive
information provided by the Kelman™ DGA **0 TAPTRANS not only
allows expensive failures to be avoided but enables asset
capabilities to be maximized. The Kelman DGA **0 TAPTRANS is a
patented designed specifically for transformers with an On-Load
Tap Changer (OLTC), which is recognised as one of the most
vulnerable parts of the transformer and which accounts for a
large portion of unplanned outages. It offers discrete multigas
on-line DGA and moisture monitoring, separating the main and
selector tanks from the diverter tank to avoid any risk of
contamination. Utilizing photo-acoustic spectroscopy (PAS)
measurement technology, well suited to field application, it
provides laboratory challenging levels of precision and
repeatability. Full 9 gas oil sampling and analysis can be
performed as often as every hour on a single tank and up to once
every three hours if all three possible oil tanks are
connected.
