      I have a query about On load tap changer employed for power transformer. I worked with MR make OLTC’s diverter switch and loading resistors for tape winding. As my understanding the diverter switch changes the polarity of windings that needs to be added to get voltage addition and subtraction. But, I believe that there are Unidirectional & Bidirectional OLTCs based on charging of transformer practiced either in both way(HV/LV for step up and step down) or only one way ( Either Step up or step down) as a understand.But,my doubt is a transformer can be used either for step up or down, But why the OLTCs are classified as unidirectional and bidirectional. Please give me detail clarification on it.
