Testing on The Grounding Resistances Measurement
At present, there are many methods of grounding resistances measurement. For example, the fall-of-potential method. It has been used widely in the measurement of building lighting protection. ZC-8 type measure instrument is the main instrument used in the fall-of-potential method. However, there are some disadvantages in this instrument, such as much error, low precision, and so on. With the development of measuring technology and the appearance of new measuring theory, We try to ameliorate it with the theory of frequency conversion, because it can effectively diminish the disturbance brought by 50Hz, which is one of the main errors in the grounding resistances measurement.
