m.hemmasi 15 دنبال کننده In the transmission grids throughout the world, voltage regulation is done at the voltage levels higher than 63 kV. Nowadays, voltage regulation is increasingly required in the distribution grid and at lower voltage levels, which has led to the voltage-regulated distribution transformers (VRDT). This was not economically possible before 2012 since available on-load tap-changers (OLTC) were just for power transformers
