NOTE
These technical data are intended for the calculator and designer of the transformer. These type-specific data are
only valid in connection with the information contained in the general section (TD 61) since this section contains
important information on such subjects as potential connection of the tap winding, leakage inductance, current
division, and so on.
Changes may have been made to a product after going to press with this documentation.
We expressly reserve the right to make changes to a product’s technical data and design as well as changes
to the scope of delivery.
In all cases, the information submitted and agreements concluded during processing of the quotation and order
in question shall be binding.
Since the on-load tap-changer is delivered to the specifications of the transformer manufacturer, the transformer
manufacturer is responsible for selecting the correct properties of the on-load tap-changer so that the requirements
of the transformer are met.

2 tap selector planes only for on-load tap-changers VACUTAP® VR I 1001
3 tap selector planes only for on-load tap-changers VACUTAP® VR I 1301,
Parallel jumpers on the tap selector terminals are then mandatory when the tap winding was wound in two or more branches
and each of these branch taps is connected to the terminals of the tap selector.
This measure reliably prevents the following.
a) Introduction of circulating currents into the current paths of tap selector and diverter switch
b) Arcing on movable tap selector contact bridges due to commutation
c) Overvoltage between adjacent tap selector terminals connected in parallel

On-load tap-changer combination VACUTAP® VRC I/VRC II
for delta connection
The VRC II 402 on-load tap-changer can also be used with the
single-phase on-load tap-changer VRC I 401 as a two-column
on-load tap-changer combination VRC I 401/VRC II 402 for
adjusting the voltage of transformer windings in a delta connection
(similar to VRC I 551 / VRC II 552 and VRC I 701 / VRC II 702).
The tap windings should correspond to those in fig. 3.

On-load tap-changer VACUTAP® VRC III 700 Y and VRC I 701/1001/1301 with multiple coarse change-over
selector (up to max. of 5 coarse taps)
Extremely fine voltage adjustment requires a great number of operating positions which sometimes may only be implemented
with a multiple coarse tapping arrangement.
For instance, 107 operating positions can be obtained by using a coarse 5-tap winding and a tapped winding with 18 tappings.
The multiple coarse change-over selector is attached to both sides of the tap selector.
The on-load tap-changers are available (on request) for Um = 72.5 up to max. 300 kV and for 2 to 5 coarse taps (tap selector sizes
B and C) or 2 and 3 coarse taps (tap selector size D).
