Abstract
We propose a scheme for traceability of digital electricity meters. For standard digital electricity meters, the analog-based method should be used. For installing digital electricity meters, the digital-based method can be used. In the process of quantization of sampling values, rounding error brings uncertainty to the computation of power. In this paper we analyze the uncertainty caused by rounding error by simulation.
