5.1.2.3.3 Monitoring of frequencies
You can select up to 10 frequencies which are to be captured in addition to the 50 harmonics included standard.
Click
the mouse on a number to enter the frequency.
Specifying the frequency monitoring for ripple control signals
The permitted frequency range is between 10 Hz and 3 kHz. Thus it is possible to both monitor interharmonics below
50 Hz as well as signal frequencies in this range.
5.1.2.3.4 Power
Advanced "Power / Energy" setting
The total power of 3-wire systems (Delta) is calculated according to DIN 40110 or IEEE 1459/3-Wattmeter method
(default).
There are multiple available methods for calculating the total power of 4-wire (star) systems.
Total power:
Standard: DIN 40110
IEEE 1459/3-Watt-meter method:

Reactive power
Using the variant standard IEEE 1459/3-Watt-meter method, the reactive power Q can be negative or positive.
