Starting Profile Plot versus Protection Limits
By means of PowerPort-E the user can call up the average current of the last five starting cycles and plot it against the
protection limits of the phase overcurrent elements that are working based on definite time tripping curves.
In order to plot the motor-start curve against the protection limits, the User has to proceed as follows:
The protective device
records the average current and voltage versus time for the last four starting cycles. This information is available via the
communications port. The PowerNet host plots the motor current versus the motor cold-start protection curve, as
shown in
