Abstract :
The paper describes new methods developed in VNIIM for the calibration of high accuracy powerline harmonics analysers at lower harmonic ratios. The possibility of measuring ratios of harmonics from 2 to 40 lower than 1% with an absolute uncertainty of less than 0.005% using known and well-characterised instrumentation for the measurement of voltage, current and active power has been demonstrated.
