| Abstract: | To reduce the cost in grounding resistance measurement of grounding grids along QinghaiTibet railway, a new grounding grid resistance measurement device was designed. When the measurement is conducted with the device, the earth surface voltage distribution is measured first to determine the spot where voltage pole is installed. Frequency conversion technology was used to avoid alternating current disturbances and to get a reasonable measurement precision. Compared with the traditional method, in which a large current is necessary, the capacity, the wiring length and the needed labor of the proposed system are reduced by 80%, 60% and 62% , respectively, with a difference in measured resistance being about 6%. |
