Summation CTs
When the currents in a number of feeders need not be individually metered but summated to a single meter or instrument, a summation current transformer can be used.The summation CT consists of two or more primary windings which are connected to the feeders to be summated, and a single secondary winding, which feeds a current proportional to the summated primary current.
A typical ratio would be 5+5+5/ 5A, which means that three primary feeders of 5 are to be summated to a single 5A meter.
