| Abstract: | In the power system, grounding is a very the electrical equipment and the safety of person. important issue. The quality of grounding is directly related to The dual-coil grounding resistance test program based on TMS320F2812 was designed, and a prototype was produced. This prototype was applied to test the loop resistances of different values. The result shows the correctness of the test program and that the prototype has a good suppression of the interferences of high frequency harmonic, low-frequency harmonic and the same frequency signal and it is very reliable. It can be used in the detection of grounding resistance of the transformer substation. |
