Function Description

Harmonic Power and Harmonic Angles
Measurement of phase angles is helpful to analyze different phenomena. It can be used for the following
purposes:
•
Evaluation of harmonic flows throughout the system
•
Identification of harmonic sources and harmonic sinks
•
Calculation of active, reactive, and apparent powers of harmonics
•
Assessment of harmonic current measurements in different points in the system
•
Modeling of disturbing loads and evaluation of their disturbing effect
•
Identification of measures to reduce the circuit feedback of the load
The device provides these measurements to support evaluation options that support the customer in mini-
mizing the influence of harmonics in the network or load, for example, when selecting the devices to reduce
the circuit feedback, filters, and reactive compensation.
Harmonic Directions
The device measures harmonics of voltages, currents, and powers up to the 31st order according to the
IEC 61000-4-7 standard.
