Abstract
The measurement of electrical energy in kWh meter becomes very important because it involves the energy transaction process. When an error occurs in it then it will cause disserve to the consumer and / or producer. This study aims to look at the characteristics of the measurement by the kWh meter, both analog and digital types, which are affected by harmonic distortion whichis mounted kWh meters. The results showed that the greater the value of the harmonics on the load it will be more damaging current and voltage waveforms (distorted). As the wave distorted bythe kWh meter, the measurement process will be far from the actual values used. In this study, the different in measurement results between Analog kWh-meter and PQA is up to 15% and Total Harmonics Distortion THD-Fi on 2200VA household consumer is40.86%. For 3500VA the difference is 9.8% with THD-Fi = 12.29%,and for 7700VA 12.8% with THD-Fi = 15.4%. On the other hand,with Digital kWh in 3500VA household consumer, the different measurement results with PQA is equal 4% with THD-Fi = 10.74%.Thus the effect on deviation measurement of electrical energy inAnalog kWh-meter is larger than in Digital kWh-meter.
