1.4 Rated withstand voltages of the internal insulation
Fig. 2 shows diagrams of the voltage stress present on the tap winding of the three primary basic connections of three-poleon-load tap-changers and single-pole on-load tap-changers.When selecting the on-load tap-changer, a check must be made to determine whether the highest stress on the tap selectordoes not exceed the related rated withstand voltages.
a0 = Between selected and preselected tapping on the diverter switch and tap selector
a1 = Between tap selector contacts of the winding of one tap position (connected or not connected)
a = Between beginning and end of a tapped winding and, with coarse tap winding, between beginning and end of a coarse tap winding.Note for coarse tapping arrangement in (-) - position of the change-over selector:When stressed with impulse voltage, the permissible withstand voltage „a“ must be adhered to between the end of a coarse tap windingconnected with the K tap selector contact and the tap selector contact at the end of the tapped winding of the same phase
b = Between the tap selector contacts of different phases and between change-over selector contacts of different phases, which are connectedwith the beginning/end of a tapped winding or with a tap selector contact
f = Between diverter switch terminal and ground
Additional for coarse tapping arrangement in (+) - position of the change-over selector:c1 = From one (-) - change-over selector contact to terminal of the same phasec2 = Between (-) - change-over selector contacts of different phases
CAUTIONAdhere to maximum ratedlightning impulse withstandvoltage stress on a0in mid-position.

Note:1) Tap selectors according to basic circuit diagram 10 09 1 W, 12 11 1W, 14 13 1 W are designed as 18 09 1 W, 18 11 1 W,
18 13 1 W.Tap selectors according to basic circuit diagram 16 15 1 W and 18 17 1 W are not available.
2) Higher values up to 550 kV on request.3) Insulation distance omitted for single-pole on-load tap-changers
The tap selector size (ID letters C,D,E) characterizes the internal insulation of the tap selector, whose rated withstand voltages mustbe matched to the requirements of the transformer winding. The admissible maximum operating voltage on the individual tapselector distances complies to half the value of the above mentioned rated short-duration power frequency withstand voltages.
