Abstract：This paper is meant to probe into the measurement methods for 10 kV distribution system. The wiring and characteristics of three‑phase three‑wire and three‑phase four‑wire measurement methods are expounded and their advantages and disadvantages are analyzed. The preferred measurement method for 10 kV distribution system proposed herein can be used for reference in design,construction,maintenance and management of the measurement system.
