Coordinated power quality measurements in public networks
23 mobile PQ measuring devices with an averaging interval of? 1 second are available for the analysis of network reactions in public networks over a period of several days or weeks. In addition to typical quality parameters, all current and voltage harmonics per conductor up to the 50th order are measured in magnitude and phase. Switchable current clamps with a current measuring range of 20A or 200A and Rogowski coils with a current measuring range up to 3000A serve as current sensors.
Four transient recorders, each with 16 measuring channels and a sampling rate of up to 1 megasample per second, are used for short-term analyses and for recording time sequences up to several hours.
The time synchronisation takes place via GPS or DCF77 signal.
