NF20 is power factor controller for reactive power compensation. It controls external reactive power element (capacitor) to meet reactive power demand of the load. This reduces burden on source to supply additional reactive current. Precise and fast measurements are useful tool for system analysis. Powerful protection function protects system and switching element in case of system faults.
