Determination of the Effect of Harmonics on the Performance of Single-Phase Low Voltage kWh Meters

Low-voltage installation systems with 450 VA and 900 VA power are one of the most commonly used electricity distribution systems in Indonesia. In the previous study, adjustments to the load of household needs were clearly made, and measurements were made at the load of 450-900 VA because some users received payment subsidies. Two types of kWh meters in accordance with standards in Indonesia are used by testing the readings of analog and digital kWh meters, which are loaded according to the load pattern. The load used is varied based on the load pattern that has been described in Table IV. Installation evaluation in the form of installing filters and improving the cross-sectional area value is carried out. After the installation of the passive filter, the power quality at 450 VA and 900 VA full load conditions improved, with the power factor in the electrical system of the 450 VA home installation increasing from 0.916 to 1.
