A university campus needs to monitor the power coming into each building and record the results at a central location. The
incoming feeds are rated at 480/277, 2000 amps, 3-phase, 4-wire Y.
An ANSI Metering Class Current Transformer, part number CR170RL-202, is selected from the CR Magnetics current trans-
former catalog to convert the full-load current down to 5 Amps for input to the transducer. The voltage legs are connected
directly to the transducer
