Peak power P
1
as
function of the con-
tinuous power P
2
The following characteristic curves show the peak power P
1
of the pick-up as a function
of the continuous power P
2
against the following variables:
• Line cable current I
L
[A]
• Line cable distance x [mm]
I
L
= 60 A,
ϑ = 45 °C, E

The following figure shows the peak power P
1
as a function of the continuous power P
2
with the following values:
• Line cable current I
L
= 60 A
• Ambient temperature ϑ = 45 °C
• Installation condition = E
1
The continuous power of the pick-up is calculated using the following formula:
2712942475
P
1
= Peak power of the pick-up
P
