摘要
To carry out monitoring of the electrical energy quality of an electrical energy supply system using an electrical power quality field device with comparatively little complexity, a method performs the steps of: detecting a first measured value of a first power quality characteristic by a measuring device of a power quality field device arranged at a measurement point of the electrical energy supply system at a first measurement time; detecting a second measured value of the first power quality characteristic by the measuring device at a second measurement time, which directly follows the first measurement time; comparing the first and second measured values with at least one predetermined threshold value; and generating an event signal, which indicates a violation of the threshold value, precisely when one of the two measured values is above and one of the two measured values is below the threshold value.
