Instructions for Impulse Operation
The maximum voltage stated in the table (page 6) can be increased for impulse operation as follows:
U
II Impuls
= U
II tamb
. q
U
II tamb
= Maximum continuous voltage at ambient temperature t
amb
q = Factor
The impulse voltage must not exceed 80% of the test voltage (winding/frame or winding/winding) or 2.5 times the value of
the maximum voltage listed in the table (page 6).

ED
≤ 3 s then q =

ED
= Pulse width
t

= Cycle time
If t
ED
= > 3 s the value of q must be obtained from the nomograph (next page).
Examples of various periodic pulse trains (energizing side)
1. Periodic recurrence of one energizing pulse
2. Periodic recurrence of two unequal energizing pulses
