<![CDATA[A base transceiver station site operates continuously, so electricity cost is a major operationalexpenditure. Two energy meters normally work in parallel at such a site: the utility kilowatt-hourmeter used as the legal basis for billing and an internal digital power meter connected to the powermanagement system for operational monitoring. A discrepancy between the two readings canreduce the reliability of bill verification. This study analyses the measurement deviation betweenboth instruments at a base transceiver station site in Lamongan Regency and evaluates the voltageprofile, current profile, and three-phase load unbalance at the same site. A comparative quantitativemethod was applied by recording both meters at four observation points within ten days. Duringthe ten-day period, the utility meter registered 2216.08 kilowatt-hours, while the digital powermeter registered 2205.35 kilowatt-hours, giving a deviation of 10.73 kilowatt-hours or 0.48 percent.This value is lower than the ±1 percent class 1 benchmark used for comparison in this study. Thevoltage unbalance stayed below two percent, whereas the current unbalance reached 29 to 46percent; therefore, redistribution of the single-phase loads is recommended.]]>
