This ILC/PT Kit contains an Ohio Semitronics model GW5-020EY267 Single Phase, 2-wire, 1 Element, AC Watt Transducer. The artifact (0 to 4) kW input is configured for (0 to 300) Volts, (58 to 62) Hz, (0 to 20) A and 4-20 mADC output. Participants will generate the following test points: 500W (250V,60Hz,2A); 1000W (250V,60Hz,4A); 2000W (250V,60Hz,8A); 3000W (250V,60Hz,12A); 4000W (250V,60Hz,16A) and read the artifact (4-20) mA output. Participants will calculate and report the measured Watts to a resolution of 0.1 W. The artifact requires line power (85-135 Vac, 60 Hz) for proper operation.
The intent of this ILC/PT is to provide a means for the participant to determine the appropriateness and effectiveness of participant practices, training, and measurement uncertainty relating to calibration of an AC Watt Transducer. Participants are expected to be familiar with calibration of, have appropriate lab equipment and have measurement uncertainties appropriate for calibration of similar devices.
