Technical data
Contact life
The expected mean contact life of the arc-carrying diverter switch contacts can be estimated according to Fig. 8, depending on
the relative load (Iu/Ium). Only approximate data can be provided, since the actual contact life is influenced by a wide range of
operational factors (this does not apply to constant-current operation).
The inspection instructions must be followed.

Technical data
Rated withstand voltages of the internal insulation
Figure 13 shows the voltage stresses at the tap winding for the three main basic connection types for three-pole on-load tapchangers and single-pole on-load tap-changers. When selecting an on-load tap-changer the maximum load at the tap selector
must be verified in order to avoid the associated rated withstand voltages being exceed.
Without change-over selector
With coarse tap selector in (+) - position
With reversing switch
With coarse tap selector in (-) - position
• a0 = between selected and preset diverter switch tapping.
CAUTION
The maximum rated lightning
withstand impulse voltage
loads at a0 in the center position must be taken into account!
• a1 = between fine tap selector contacts of the winding for one step (closed or open)
• a = between start and end of a fine tap changer winding; for versions with coarse tap changer winding also between
start and end of a coarse tap changer winding.
Note for coarse tapping in (-) position of the change-over selector:
For loads involving impulse voltage the permitted withstand voltage "a" between the end of a coarse tap changer winding connected to fine tap selector contact K and the fine tap selector contact at the end of the fine tap changer winding of the same phase must be taken into account.
• b = between the fine tap selector contacts for different phases and between change-over selector contacts for different
phases connected to the start / end of a fine tap changer winding or a fine tap selector contact.
• f = between diverter switch lead and ground
Additionally for coarse tapping in ( + ) position of the change-over selector:
• c1 = from a ( - ) change-over selector contact to the lead for the same phase.
• c2 = between ( - ) change-over selector contacts for different phases.

Technical data
On-load tap-changer OILTAP®M III 600 Y ... M I 1503 with coarse tap selector (up to 5 coarse taps)
Fine voltage regulation requires a large number of operating positions that may necessitate
a multiple coarse tapping arrangement.
For example, with a 5-stage coarse winding and a fine tap changer winding with 18 tappings,
107 operating positions can be achieved.
The coarse tap selector is attached to both sides of the fine tap selector.
The on-load tap-changers are available for Um = 72.5 ... 300 kV and for 2 ... 5 coarse taps (tap selector size B, C and D).
Multiple coarse tap selector
• a0 = between selected and preset diverter switch tapping
• a1 = between fine tap selector contacts of the winding for
one step (closed or open)
• a = between start and end of a fine tap changer winding and
between the closed K-contact and any points of the fine tap
changer winding for the same phase
• b = between the fine tap selector contacts for different phases and between the closed K-contact of a phase and any
points of the fine tap changer winding for another phase
• c1 = between any coarse tappings for a phase and the diverter switch lead for the same phase
• c2 = between corresponding open coarse tappings for different phases
• d1 = between closed and adjacent coarse change-over selector contact in a phase
• d2 = between open adjacent coarse change-over selector
contacts in a phase
• d3 = between start and end of all coarse taps in a phase
• f = between diverter switch lead and ground

3.1
Parallel bridges for parallel connection of tap selector planes
Only for on-load tap-changer OILTAP®M I 802 (803), M I 1203/1503 (see section 3, drawing no. 899598)
For current division at the terminal contacts of the tap selector associated tap selector planes are connected in parallel, i.e.
• 2 tap selector planes for on-load tap-changer M I 802 (803),
• 3 tap selector planes for on-load tap-changer M I 1203 / 1503.
Parallel bridges at the tap selector terminals are required if the tap winding is wound in two or more strands and each of these
strands taps into terminal contacts of the tap selector.
This measure reliably prevents
a) carry-over of compensating currents into the tap selector and diverter switch circuits
b) arc occurring during commutation at moved tap selector contact bridges
c) overvoltages between adjacent tap selector terminals connected in parallel
3.2
On-load tap-changer OILTAP®M I 603 and M I 803 with 3-sector diverter switch
On-load tap-changer models M I 603 and M I 803 @@ are supplied with a 3-sector diverter switch, if required.
This results in a higher step capacity (see Fig. 10) and/or a higher contact life of the arc-carrying diverter switch contacts.

On-load tap-changer OILTAP®M I 502 and M II 502 for 16 2/3 Hz
On-load tap-changer models M I 502 (single-pole on-load tap-changer for single-phase transformers in any configuration) and
M II 502 (two-pole on-load tap-changer for single-phase transformers with center-tap connection) are available for application
in traction supply transformers with an operating frequency of 16 2/3 Hz. The on-load tap-changers are equipped with a special
diverter switch. The tap change operation sequence and the dimensioning of the transition resistors are adapted to an operating
frequency of 16 2/3 Hz (technical data are available on request).
3.4
Two-pole on-load tap-changer OILTAP®M II 352/502/602
On-load tap-changer M II 352/502/602 is available as a two-pole on-load tap-changer for single-phase center-tap connection
with technical specifications corresponding to on-load tap-changer M III 350 Y, M III 500 Y or M III 600 Y (see dimensional drawings, section 4).
On-load tap-changer combination for delta connection (example)
On-load tap-changer M II 352 can also be used in conjunction with single-pole on-load tap-changer M I 351 as a two-column
on-load tap-changer combination (M I 351/M II 352) for voltage regulation of transformer windings with delta connection (correspondingly with M I 501/M II 502 and M I 601/M II 602). This combination is referred to as M III K, see Figure 17.
The tap windings must be based on Figure 17.

On-load tap-changer OILTAP®M III 350 Y...M I 1503 for linear voltage regulation, up to 34 operating positions
The high number of operating positions is achieved without change-over selectors through doubling of the tap selector contact
planes compared with the standard version (leading to extended installation length).
The on-load tap-changers are available for Um = 72.5 ... 300 kV and several tap selector sizes (rated withstand voltages and dimensional drawings are available on request).
