Ground sensor current transformer cable routing - Siemens USA current transformer is commonly referred to as a zero-sequence current transformer, even though it is only on means to monitor zero-sequence currents. When there are too many cables for one zero-sequence ground current transformer, multiple zero-sequence CTs can be used.
