Automatic Step Voltage Transformer

This is the most present day outline Automatic Step Voltage Transformer is used to amend the variety in HV supply voltage. These are accessible in three voltage go I. e. 6 KV, 11KV, 33KV and 132 KV. This sort of controller amends the supply voltage by methods for on stack tap changer switch.​ It just requires 60 seconds for full range remedy of voltage, while traditional write controllers require 6-8 minutes time for full range voltage redress. On the off chance that the variety of info high voltage is inside 15-20% of the evaluated voltage; the progression down transformer can be given on-stack tap changer.
