A range of current transformers to summate currents from various current transformer secondary sources and provide a proportional current output. The TAEA may be used to summate CT inputs of the same, or different, ratios. When summating three phase circuits, it is necessary to summate like phases ie L1-L1, L2-L2, L3-L3.
