IP = 100 A IS = 100A IP = 150 A IS = 150A
IP = 300 A IS = 300A IP = 600 A IS = 600A
The value for Ip,max indicated in the Specification is valid for currents
from a few ms on. For shorter duration (e.g. short circuit current) the
currents are transformed directly and can therefore be higher than
Ip,max. This will curtail the accuracy but can be used for kick-offs.
Example : Avariable Offset ripple reduction means a low pass
The offset ripple can be reduced by an external low pass. Therefore a capacitance C
a
must be switched parallel to R
M
. The diagram shows the
remaining value of the offset ripple (i
