MAKING THE MEASUREMENTS
Thousands of design and test engineers trust Voltech power analyzers to provide
clear and definitive measurements when testing large power transformers. Our power
analyzer range is ideal for large transformer testing because the analyzer is easy
to use and provides accurate measurements such as power (watts), Vrms, Vmean, low
power factor readings, K-factor and corrected power can also be displayed directly
using the PM6000 math function.
To test power transformers in accordance with IEC60076 or IEEE/ANSI C57, accurate
power measurements are required at no-load conditions where the power factor is
very low (<0.01). Transformer k-factor and corrected power measurements require
simultaneous rms and corrected mean voltage measurements.
The analog design of the PM6000 power analyzer ensures that its voltage and current
channels are carefully matched, providing optimum performance at low power factors
and its powerful digital processors provide simultaneous rms and mean voltages in
real time from exactly the same samples.
LARGE POWER TRANSFORMER TESTING, RIGHT FIRST TIME
- Power (in watts) is measured with no load on the transformer.
- ‘No-load’ losses include core loss, dielectric loss, conductor loss in the winding
due to excitation current, and conductor loss due to circulating current in parallel
PM6000 - Multi Phase Power Analyzer
- analog design ensures that voltage and current channels are carefully matched.
- optimum performance at low power factors.K-factor and corrected power can also be
displayed directly using the MATH function of the PM6000.Measure turns ratio directly
using the math function.
- 0.02% basic accuracy for definitive power loss and efficiency measurements,outstanding
rejection of common-mode signals.
