5. Transformers are the most important components of electrical energy supply networks. They
raise or lower voltage levels at substations.
It is critical to perform transformer maintenance periodically, although the transformers has
long life cycle and low failure rate.
BERR provides installation, testing, commissioning, maintenance, engineering and consulting
services throughout the transformer life cycle, from selection commissioning to recycling, for all
brands and kinds of transformers.

connections. Control of grounding connections.

8. Maintenance can either be time-based or condition-based, depending on the service strategy
selected. The time-based maintenance is carried out at predetermined intervals of time or on
the base of prescribed criteria and aimed at reducing the probability of failure or the working
deterioration of the element.
Power transformers are the most important components of electrical energy supply networks.
Although these components have high reliability, failures can occur due to external factors such
as short circuits in the grid. Failures can also occur due to ageing effects of the active part,
especially the insulation system, or ageing of important accessories such as bushings or on load
tap changers.
