Summary: | An on-load tap changing apparatus which suppresses an arc at the time of switching, reduces deterioration of a switching unit, and has an excellent durability is provided. This on-load tap changing apparatus includes a first switching unit 2 connected to a first tap 91 of a transformer 9 provided in a power system and switching power supplied from the first tap 91, a first impedance changing unit 5 connected in series with the first switching unit 2 and increasing an impedance when the first switching unit 2 executes a switching operation, a second switching unit 3 connected to a second tap 92 of the transformer 9 and switching power supplied from the second tap 92, and a second impedance changing unit 6 connected in series with the second switching unit 3 and increasing an impedance when the second switching unit 3 executes a switching operation. |
