Choke module for suppressing ferro-resonance


In three phase voltage networks with isolated neutral point which use single-pole voltage transformers, ferro-resonance may occur. These resonances are generated by the concur of single-pole voltage transformers non-linear inductance of open-circuit operation and the earthing capacitance of the network.
