1 Intrducing a New Prtable Revenue Meter Calibratin Instrument Ming T. Cheng Directr f Asian Operatins Lexingtn Drive Knxville, TN USA Phne: mingtcheng@pwermetrix.cm

2 3 Series Overview The NEW PwerMaster 3 Series is a highly advanced, yet ecnmical slutin fr testing metering sites in the field under actual custmer lad cnditins.

3 Brief Histry f Pwermetrix Funded in Knxville, TN USA Intrduced the Pwermate 330 First True 3-Phase Analyzing Standard in Nrth America that Measured Full Harmnic Cntent Merged with Technlgy fr Energy Crpratin 4 Divisins - Electric Pwer, Nuclear, Materials Testing & Aviatin Intrduced the Pwermate 730 Pwermate 330 with Integrated 3-Phase Current Surce Intrduced the PwerMaster 7 & 5 Series State f the Art Technlgy, Accuracy & Functinality Intrducing the PwerMaster 3 Series State f the Art Technlgy, Lightweight, Basic Functinality

4 3 Series Overview Testing under custmer lad cnditins at the metering site is the best way t determine if a custmer is lsing revenue. Revenue lss is mainly caused by the fllwing errrs: Incrrect Wiring Bad Current Transfrmers (verburdened, shunted, mislabeled, incrrect installatin) Bad Ptential Transfrmers (verburdened, mislabeled, incrrect installatin) Bad Meters (nt accurate under nrmal perating cnditins at the custmer s site) Administrative Errrs (wrng billing multipliers) Theft

5 3 Series Overview Errrs are everywhere, especially n three phase sites with instrument transfrmers. On the average, arund 5% f these sites have sme srt f errr. On the average, each errr can cst a custmer arund $25, USD.
