Introduction
Scope
The purpose of this user guide is to describe the use and capabilities of the
PA2553
and
PA2553E
(External Current) Three-Phase Power Analyser.
The three-phase
PA2553
is an easy-to-use, general purpose power analyser, which may
be configured for 1
φ
2-wire, 1
φ
3-wire, 3
φ
3-wire or 3
φ
4-wire power sources and loads.
Overall, the
PA2553
analyzes the electrical power delivered to or by a device. The unit
can be quickly set up on your bench top. You can adjust the viewing angle using the
handle and adjust the contrast from the configuration screen.
The
PA2553
Option E provides support for external current transducers of the
current:current or current:voltage type. This option also provides terminals at the rear
panel allowing the user to power external circuitry from the
PA2553
’s internal DC power
supplies (positive and negative 15V).
Both the
PA2553
and
PA2553E
analysers display voltage, current and wattage "results"
in numeric and graphic waveform formats. Results include voltage, current, wattage and
harmonic frequencies in absolute, percentage and phase. You may display the
fundamental in a bargraph format through the 40
th
harmonic or in a listing format through
the 50
th
harmonic. You may examine power waveforms graphically and chart historical
results in divisions of time from seconds to days. Additional screens display voltage and
current peaks, harmonics, averages and reactive power with K-factor and crest factor of
the voltage or current signal.
All of the data that can be displayed on the
PA2553
/
PA2553E
screens can be printed in
full-page printout formats. Refer to Printing Results page 51 . Note that both bargraph
and listing fundamental printouts contain the 2
nd
through the 50
th
harmonics.
