Abstract :
The paper presents the results of further investigations, carried out under the aegis of the Utilization Research Committee of the former Central Electricity Authority and Area Boards, into the load/consumption characteristics of domestic consumers´ installations. These are combined with the results of the pilot tests giving over 400 sets of data, and their influence upon the performance, utilization and design of integrating meters is discussed. A system of weighting the errors found in `off-service¿ sample meter tests at certain load currents is proposed in order to arrive at the error of total energy measured, and a formula is given for the economic service period. Suggestions are made for the setting of a recertification period by reference to the statistical distribution of meter `weighted¿ errors as determined by sample tests at specified load currents. A possible revision of the standard ratings of meters is discussed, and proposals are made for the better utilization of existing meters to achieve maximum service and recertification periods.
