Abstract :
It is an effective method for detecting and evaluation substation´s grounding grids with break and corrosion to measure magnetic induction intensity. But it will be faced with complicated EMI problem to measure effectively magnetic induction intensities in substation. So power frequency harassment and transient EMI caused by switching operations are measured practically in a few substations. These EMI characteristics are analyzed and given. The detecting system, including hardware device of data measurement, diagnosis and analysis software, was introduced concisely. The results of applications show that this system can satisfy the practical engineering.
