On-load tap changer
transformers are the basic devices that provide voltage stability in energy
The most crucial point of tap
changing under load is the uninterrupted and safe supply of energy to the load
during the process of changing the voltage from one value to another.
On-load tap changer; It should
be able to safely perform this operation even under the most severe operating
It is necessary to change the
oil, measure the contact transition resistances and measure the wear on the
contacts at certain intervals (maintenance times are indicated on the label) of
the equipment operating under these heavy conditions.
These operations are carried out by our
expert teams in the field and in case the transformer is in the workshop
