Abstract — A class 0.2 electricity meter for d.c. applications is
being designed at SP Technical Research Institute of Sweden. The
aim is to verify that suggested requirements for HVDC electricity
meters can be fulfilled within a reasonable design and production
cost. The suggested design is built on a high-resolution ADC and
hi-impedance low-offset input circuits. This paper contains an
analysis of how to implement the requirements for HVDC
metering in a meter design.
