Power Measurement
Suitable for

PM

DEWE-PM
Key Features Software
t Measurement of DC, 1-, 2-, 3-, 6- and 7-phase AC
systems
t 16.7 Hz, 50 Hz, 60 Hz, 400 Hz, 800 Hz,
variable frequencies (1.5 Hz up to 10 kHz)

Beside the calculation of power for the fundamental
oscillation and all signals, questions of harmonics, symmetries, flickers and start-up processes arise.

t Multiple power measurements with one device

Switching frequencies of drive mechanisms having
several kHz require sampling rates of several hundred
kHz and analogical bandwidths of input amplifiers. The
demand of preciseness is far below 0.1 % and this
should preferably be the case in the entire frequency
spectrum and amplification range.

t Power quality library for FFT, harmonics, higher
frequencies, flicker, flicker emission, symmetrical
components etc. and automatic report generations

t Math-library for efficiency, energy consumption,
recuperation calculation

t Calibration in frequency domain
Key Features Hardware
t High bandwidth up to 6 MHz
t High accuracy 0.02 %
t High sampling rate up to 10 MS/s
t Continuous data storing in full sample rate
t Flexiblity in number and type of input channels

In times of power electronics, power measurement is not
only a multiplication of current and voltage, but primarily
an analysis of interfering high-frequency and broadband
signals. Sinusoidal qualities, as once electric current
and voltage, are displaced by pulse packages; power
ratings do not have only 50 or 60 Hz any longer.
