AB This article proposes a measurement solution designed to monitor the instantaneousfrequency in power systems. It uses a data acquisition module and a GPS receiver for time stampingand traceability. A Python-based module receives data, computes the frequency, and finally transfersthe measurement results to a database. The frequency is calculated with two different methods,which are compared in the article. The stored data is visualized using the Grafana platform, thusdemonstrating its potential for comparing scientific data. The system as a whole constitutes anefficient, low-cost solution as a data acquisition system.
