ABSTRACT:
Apparatus for determining the size adequacy of a current transformer in an electrical power distribution system. The apparatus includes a voltage generating source for connection in series with a current transformer secondary circuit, which source saturates the current transformer. A first signal is provided which is indicative of the voltage required to cause the current transformer to enter saturation. A second signal is provided which is indicative of the resistance of the secondary circuit of the current transformer after saturation. A third signal is then provided which is responsive to the product of the second signal and predetermined constant value. A ratio of the first to the third signals which exceeds unity indicates adequacy of the current transformer for a given system.
