Product overview
S11 series 33kV class On-load voltage regulation is a voltage regulation method by which a transformer can change the voltage bychanging the tap gear when operating under load.Powerelectronic component switches have the advantages of frequent switching,no spark and long service life,so they can be used as on-load tap-changer for distribution transformers.
