Typical Application
OVER/UNDER CURRENT MONITORING
This illustrated a typical application for monitoring current to a 3-Phase motor. External current transformers are
attached to each of the three incoming power lines. The secondary leads from each current transformer are
routed through the window openings in the transducers. A standard 5 Amp secondary current transformer is
recommended to be attached to a transducer rated for 5 Amp input. With the transducer attached to a PLC the
over/under current and phase loss conditions can be monitored.

Typical Application
LOOP POWERED AC CURRENT TRANSMITTERS
Looping the primary current-carrying wire several times through the window opening may change the scaling
factor. The “actual” measurement range will be the name plane rating of the transducer divided by the number of
wire passes. For example, the CR4220-30 has a name plate rating of 0-30 AAC. Three passes of the wire
through the window opening will then provide an effective range of 0-10 AAC (30/3).

Typical Application
POWER TRANSDUCER
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 must be selected on convert the full-load current down
to 5 amperes for input to the transducer. Part number CR170RL202 is selected from the
current transformer catalog. Since the transducer is rated to carry the full line voltage,
connection is made directly to the transducer without the use of an external voltage transformer.
