Flick. RIntroduction to voltage regulation. Voltage load regulation is to maintain a fixed voltage under different load. Voltage regulation is limiting factor to decide the size of either conductor or type of insulation. In circuit current need to be lower than this in order to keep the voltage drop within permissible values. The high voltage circuit should be carried as far as possible so that the secondary circuit have small voltage drop. Go to Content Voltage Regulation for 1.
