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 CR4170 True RMS Current Transducer. 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. OVER/UNDER CURRENT MONITORING Looping the primary current-carrying wire several times through the window opening may change the scaling factor. The “actual” measurement range will be the nameplate rating of the transducer divided by the number of wire passes. For example, the CR4220-30 has a nameplate 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). LOOP-POWERED AC CURRENT TRANSMITTER DC current may be monitored by using the voltage transducer attached to a resistive shunt. The illustration shows a CR5310-.05 transducer with an input range of 0-50 mv attached to a standard 50 mv resistive shunt. The output is attached to a standard 0-5 Vdc panel meter. DC CURRENT MONITORING 36 transducer03a Typical Applications This illustrates a typical application for monitoring the voltage supply to a motor. The transmitter is attached to the incoming voltage supply leads. Use the CR4600 or CR4700 series for an AC supply and the CR5300 series for a DC supply. The transmitter output is attached to standard 4-20 ma, loop-powered panel meter. The transmitter may also be attached to a PLC to monitor for over/under voltage and phase loss. VOLTAGE MONITORING A plant manager needs to record the total charge to a bank of batteries. A CR5210 DC Current Transducer is attached to one of the incoming current lead and a CR5310 is attached to the incoming voltage lines. The output from each transducer is attached to a 0-5 Vdc analog input module on a PLC. The PLC computates the product of the current and voltage for the total power useage.
