Abstract

This paper describes the implementation of a system for the generation and measurement of DC power and energy for voltages with magnitudes up to 800 V DC and currents up to 400 A DC. Power generation is based on the "phantom" power approach, where the voltage and current of the applied power are generated by separate voltage and transconductance amplifiers. Power and energy measurements are performed using a portable, DC transfer reference meter (TRM), consisting of commercially available instrumentation and transducers. Details of the system design, measurement techniques, and significant sources of error are presented.
