The concept of contract Condition Monitoring is to monitor the change
in a machine's condition and reduce the chances of any catastrophic
failures and loss of production.
With the ongoing reduction of maintenance staff and budgets and the
necessity to maintain production levels at their maximum, product
and maintenance engineers are under constant pressure to reduce downtime.

In many companies, expensive condition monitoring and correction
equipment has been purchased together with ongoing expensive
training. After a period of time the equipment is often left
unused due to reductions in maintenance staff or changes in
job roll requiring to be undertaken again at a later date.

| TRANSFORMER OIL MAINTENANCE |
To ensure that transformer oil deterioration does not lead to the damage
of winding insulation, it is necessary to test the condition monitor
the oil on a regular basis.
A Dowding & Mills engineer will visit to take samples of oil for
analysis. This can usually be done without any interruption of the supply.
The samples are then fully laboratory tested to British Standard BS
5730: 1979.
The tests entail checking electrical strength, acidity, water content,
colour, fibre content, sediment content and general condition.
A full report is issued giving recommendations of any remedial action
required.
If the oil is contaminated, it is often better
to filter the old oil than renew, as the new oil may become contaminated
immediately from moisture and sediment remaining after the tank has
been drained. Using portable equipment and mobile generators even
the remotest transformers can be reached.
Dowding & Mills provides the complete service for security gates,
barriers, turnstiles, road blockers, sliding doors, powered window
vents, and rising bollards. This comprises site surveys, installation
