In scope of product safety concept, all products intended to be placed on the market, supplied, made available on the market or put into service must be safe and in compliance with the relevant technical regulation. Similarly, the active electricity meters should be safe and convenient. Sometimes, although the products like as electricity meters which have the high error rates which are close to limit level of legally permissible error margins, they can be safety and in convenient legally. In such a case, the impact of these electricity meters on distribution companies and meter subscribers using energy above the average value can be more in terms of cost, negatively. Also, due to the increasing energy demand and cost, the awareness of saving planet is continuously increasing in the society. Therefore, the usage of product like as electricity meter which is produced with minimum rate of operating error becomes more meaningful, nowadays. In this context, aim of this study is to examine the impact of some variable parameters such as harmonic distortion rate and meter constant except of current shift, voltage shift, frequency shift and temperature variation on comprehensive maximum error (CME) of the electricity meters with same basic technical specifications. At the end of study, it is observed that the large variability of some working error rates of an electricity meter may be caused by reasons such as different production design according to working area, materials which have different sensitivity, quality, working range and also different measurement methods.
