The measurement of vector voltage can be got from the discrete sequential data of a sampled singal. This paper expounds the fundamental principles of vector voltage measurement using a sampling method, and deduces the calculating formula. The possibility of engineering application for the formula has been proved rigorously in theory, and it can bring much convenience to system realizing. Combining with compute technologies, the author puts forward a microcomputer based digital vector voltage measurement system.
