Problem description After installing a second photovoltaic system on a low-voltage grid with a high proportion of inverters, frequent faults were detected in the first and larger solar system. The inverters of this system, but also of the newer PV system, frequently switched off with the message “grid fault”. During a grid quality measurement carried […]
Camille Bauer Metrawatt AGIntro Energy transition and climate neutrality Before we get to the topic of “towards condition-based maintenance”, here is a higher-level digression. Namely, discussions about climate neutrality have reached a new evolutionary stage. This means that nations are actually addressing it extensively politically. Whereby it is also clear that the competence of political intentions is not […]
Data center data security reliability depends on many different factors. For example, from the energy supply and operational reliability of the power supply. This is what we refer to in this blog as electrical data security. Electrical data security conditions must be constantly monitored to achieve Tier 1 – 4 levels. It is advisable for […]
