capable of designing, installing and maintaining medium voltage
distribution systems upto and including 11000 Volts.
ESTIL can supply and install both new and reconditioned switchgear
and transformers with full warranties being offered on all reconditioned
ESTIL offer a full maintenance service including switchgear
inspection and functionality checks and oil tests which can quickly
establish if there are any underlying problems within transformers.
Switchgear is often left for years with little or no maintenance, it is
essential that switchgear is maintained regularly to ensure that it will
operate correctly when it is required to do so, Estil can carry out a
planned maintenance programme on all M.V switchgear.
Simple analysis of the dissolved gases within transformer oil can
prevent a future catastrophe which could lead to transformer failure
and/or possible damage to connected plant.
Recent oil tests carried out for some of our customers discovered
faults on tap change switches. This was causing the transformers to run at
a higher than normal temperature and was causing instability in the
secondary voltages which in turn was causing plant to trip. The tap change
switches together with the transformer oil were replaced, this resulted in
the problems being resolved.
