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