1. Introduction
SP-1001P single phase Portable Testing Equipment is a new generation, high stability single phase energy meter calibration phantom load power source. It uses the advanced technology and electronic components available in 90 decade. The instrument can generate sine-wave voltage/current and phantom power to drive single phase energy meter, usually it is the main part of energy meter test bench.
