Abstract
The change in performance of induction watthour meters when measuring integral-cycle-controlled resistance loads was studied. A simple mathematical model is used to explain the main cause for error. Test results for representative meters show that meters on integral cycle speed up, resulting in substantial positive errors. When mixed loads are monitored, the error becomes small and within commercially acceptable limits.Keywords
