Precision power analyser

The PPA2500 power analyser series from Newtons4th is designed to combine flexibility with ease of use, making it possible to view primary measurements instantly by pressing just one of six mode keys.
The power mode displays all primary power functions with both total and fundamental values, plus the phase relationship to phase 1 Volts. In the three-phase mode, all primary power functions can be viewed simultaneously on all three phases. DC power and selected harmonics are also displayed for all phases, giving instant information on the DC and harmonic power content.
Integrator mode presents true and fundamental values of all integrated values. Any individual phase or the sum value of all phases can be viewed. Conveniently, other measurement modes can be viewed while integration continues in the background.
In harmonics mode, realtime harmonic analysis to the 76th harmonic is made simultaneously on both voltage and current inputs. THD computation with either series or difference formula is set with any selected number of harmonics up to 76. TIF computation is included as standard. The display can be switched between graphical, tabular or realtime displays, while measurements are made, without loss of any data.
In addition to the true RMS value of voltage and current on any measurement channel, RMS mode also provides realtime measurement of DC, AC, peak, crest factor and surge. With a three-phase display, all values can be seen on all phases for easy phase to phase comparisons.
The oscilloscope mode provided by the PPA2500 is a valuable aid in development and testing. Display of voltage and current on a single phase or all three phase waveforms can be selected, with user control of trigger level, pre trigger, time base and cursors.
Utilising realtime DFT analysis, the analyser provides precision impedance measurements on any individual phase or a simultaneous display of all three phases. Resistive and reactive components of the total impedance are presented along with the phase angle of each phase impedance and the fundamental frequency.
The PPA2500 is available as a single-, two- or three-phase precision power analyser. For applications requiring four-, five- or six-phase power measurement, it can be operated in master-slave mode for fully synchronised analysis.
