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.
