Frequently Asked Questions

What does this instrument measure?
It simultaneously measures single- or three-phase RMS voltage, average voltage, RMS current, active power, power factor and frequency — the parameter set needed for transformer no-load and load loss measurement.
How is it different from a power quality analyzer?
A transformer power analyzer is built for measuring electrical parameters during transformer routine tests and is designed per JB/T 501 and GB 1094. A power quality analyzer focuses on grid-side phenomena such as harmonics, voltage sags and flicker. They serve different purposes.
Which transformer tests use this instrument?
Transformer routine tests, no-load loss and load loss (short-circuit impedance) measurement, and factory inspection, per JB/T 501, GB 1094 and IEC 60076.
