144.ANALYSIS OF AFFECTED PHENOMENA ON ELECTRONIC OLTC DESIGN FOR DISTRIBUTION TRANSFORMERS

Abstract

Voltage regulation is nowaday usually reserved for regulating the voltage on HV and MV network. By including more and more of distribution generation automatic voltage regulation on distribution transform­ers becomes an undeniable need. At the moment mostly used type of tap-changer is electromechanical. However in a recent time there are a lot of researches about electronic OLTC (on-load-tap-changer) due to their advantages over electromechanical switches. Since electromechanical switches are robust, respond slower, and operate from tap-to-tap, there is surely a need and a reason for investigation and consequently application of the electronic OLTC in a dis­tribution network in a close future.
