Lumel extCZIP®-PV PRO - integrated protection and control relay dedicated to photovoltaic and wind farms

The extCZIP®-PV PRO relay is intended for switchgear operating at the connection points of photovoltaic plants to the MV or LV distribution networks, as well as for the micro-installations. The device meets all requirements regarding power system protection for PV plants, specified in the Grid Code of the Polish Distribution System Operators (IRiESD) and the PN-EN 50549-1 and PN-EN 50549-2 standards. It includes protections supplied from both MV and LV voltage circuits.
To perform the required functions, the new relay is equipped with additional inputs for voltage and current measurement at the LV side.
