Param. Description
E-max Maximum e.m.f. voltage.
This parameter allows the determination of the working
point on the excitation curve that would be reached with the
entered settings.
Peak instantaneous error at voltage E

1. If CT Analyzer is not able to measure up to the actual value, the prefix ">" is displayed to indicate that the measurement value
is larger than the displayed value.
2. If parameter "Spec." is set to "by Duty" in the CT-Object card (see page 101), no calculation is performed for this parameter if
the user did not specify values for T
3. This parameter is only displayed if parameter "Spec." is set to "by Duty" in the CT-Object card (see page 101). No calculation
is performed for this parameter if the user did not specify values for T
