HOW TO CHOOSE A CURRENT TRANSFORMER (CT) FOR THE FRONIUS SMART METER
There are a few decisions to be made when selecting Fronius (CT’s) current transformers :
Primary and secondary side ratings
Type – In most cases, opening or split core CTs are the preferred choice because installation is much easier.
Note: some split core CT’s are not designed for outdoor use or harsh climate conditions where contact with moisture can cause rust development. In humid environments spraying a rust inhibitor such as WD40 on the exposed laminations can help to prevent rusting. For monitoring power on metal buss bars either a bussbar or flexible rope style CT can be used.
CT accuracy ratings should be based on your specific application needs. For monitoring basic consumption or loads, accuracy is typically not as critical
Revenue grade CT’s provide a higher level of accuracy at lower amperages and will improve system performance in zero feed – in applications.
It is critical that the opening in the CT is large enough to fit around the conductor that is being monitored
