Phase and zero-sequence current sensing modules mounted together on a cable bushing

摘要

A current sensing modular system, which allows sensing the phase current and/or the around-fault or zero-sequence current, having to that end at least a first module having at least one phase current sensor embedded therein and a second module having a zero-sequence current sensor embedded therein. The first module is independent of the second module, both modules being installed directly in the connection elements, i.e., in the connection point between at least one bushing and at least one connector of at least one grid cable.
