Medium Voltage

ESTIL are 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 equipment.

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.
