Abstract :
In this paper, a standby power test system for the measuring low level power with non-sinusoidal signals, which utilizes two synchronized high precision digital voltmeters, is described. The signals of normal voltage and low level current waveforms were computed from digital samples and compared with the values obtained from thermal converters. An electronically aided low-current multistage current transformer for precise measurements of standby current was used. The system can be used as a reference system for calibrating standby power analyzers at power frequencies.
