With fluctuating data occurring when connecting to interconnected systems, or with motor evaluation*, in certain circumstances you may need to capture rapidly changing phenomena (such as during load fluctuations in a motor). These tasks can be handled effectively with the cycle-by-cycle measurement function. The function takes measurements of parameters such as voltage, current, and active power for each cycle, then lists the data on screen in a time series. Up to 3000 data (measurements of signals from 0.1 Hz to 1000 Hz) can be saved in CSV format. * Requires the motor version (-MV)

Example of calculation with the cycle-by-cycle function

This function enables measurement of voltage fluctuations/flicker in compliance with EN61000-3-3 and IEC61000-3-11. It can measure relative working voltage change, maximum relative voltage change (dmax), relative voltage change time (dt), short-term flicker value (Pst), and long-term flicker value (Plt). The initial limit values for the individual parameters are set in accordance with the IEC standard.
