In a Tap changing transformer where is the tap connected ,
is it connected in the primary side or it is connected in
secondary side
Answer Posted / javedhanif
Tap Changer is always installed at HT side,since at HT side
current is low .
reasons for not installation at LT side
1.high current
2.when we have to change the tap there is little bit
sparking, and sparking cause gas production ,thus buchhloz
relay operate.
