800A AC output
Note: The signal for the 800A AC output is generated by an internal
transformer. To avoid saturation, sudden magnitude changes are
suppressed and the signal is output as a ramp. For several
applications the magnitude change is deferred even more, for
example, for CT ratio measurements.
The ramp changes for a full magnitude are
• one period of the signal, regardless of the size of the change for an
increase ramp
• 300ms for a decreasing ramp, or accordingly less if the magnitude
change is only a fraction of its full value.
