Current Transformers

For Fronius Smart Meters

The solution for larger PV systems: The easy-to-connect Fronius Smart Meter CT current transformer can be used to measure higher currents without having to disconnect the power supply.
This is possible thanks to its split core technology where the transformer is placed around the cable to be measured without the need to disconnect the cable for installation.
The transformer converts the measured current into a signal that can be measured by the Fronius Smart Meter. The Smart Meter then converts the signal to the original primary current using the conversion ratio.
The result is reliable measurement of key data, enabling even larger PV systems to be optimised.
