Summation Current Transformer.
Current transformers to summate currents from various
current transformer secondary sources and provide a proportional current
output. They 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 R-R, Y-Y, B-B.
2, 3 or 4 inputs of 5amp
output 5amp
