摘要：
The influence of load variations on the performance of four different types of demand meters was studied using a computer controlled test system capable of reproducing load profile data recorded in the field. Results of the tested meters are compared with computer calculated demand values based on readings of a fast responding reference multimeter. Differences in readings in the range of -9.3% to +5.3% were observed during the tests of the four demand meters. For the load profiles considered, demand calculations based on one minute sub-intervals resulted in values closer to the true peak demand than calculations with five minute sub-intervals.
