On-Load Tap Changer Maintenance

On-load tap changer transformers are the basic devices that provide voltage stability in energy systems.

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 conditions.

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 environment.
