Continuous Phasor Recorder (CPR)

The continuous recorder for complex phasors – Continuous Phasor Recorder (CPR) – stores the
frequency and the complex phasors of currents and voltages of the fundamental component as
an instantaneous value at the end of the parameterized cycle time. No averaging is performed.
Figure 7-23 Principle of storing the instantaneous values with the CPR
The phasors are used to calculate the derived values for the corresponding recording time with
OSCOP P.

Note
Only one frequency per measured value group of a DAU is stored even if monophase has
been configured.
