Three-phase Current Transformers

The Model 276B3 is a ring-type 3-phase transformer for currents from 50-1200 amps. Secondary terminals are #8-32, brass studs with one flatwasher, lockwasher and regular nut. Polarity markings are stamped on the transformer. Holes at the corners of the transformer case are for attaching a mounting... [See More]

The Model 276C Current-Canceling Transformer monitors two of the three phases, and cancels the effect of the current signal in the third phase, which would otherwise cause a phase shift error. The Model 276C accepts input directly or from two standard current transformers (CTs), corrects for the... [See More]
