Tap-changer know-how: Enhancing the switching capacity of change-over selectors with minimized gas production
Rainer Frotscher

Sažetak
The article discusses methods to reduce the recovery voltages on the open change-over selector contacts. The generation of arcing or sparking gases can be minimized increasing the contact opening speed of the change-over selector. Using an additional snap contact, it can be assumed that the transformer DGA will not be influenced by the change-over operation.
