Product Info

De-energized tap changers are used for voltage regulation of oil-immersed transformers within certain limits. The required winding taps must be set with the transformer switched off.
The universal PBVKL series of de-energized tap changers is designed for mounting on the cover of the transformer and includes three main types - PBVKL01, PBVKL02, PBVKL04.  All are designed, manufactured and tested according to the requirements of the International Standard IEC 60214-1.
