JIN Bai-rong, LI Dian. The Impact of Power Grid Harmonics on Grounding System of Arc-suppression Coil[J]. High voltageapparatus, 2009, 45(4): 159-162.DOI:
In order to test the performance of new type automatic tuning arc-suppression coil of some factory
the metal grounding、 resistance grounding and arc grounding test of arc-suppression coil whole set tests were carried out.By analyzed the test result
abundant harmonic component was discovered in single-phase grounding current when power grid have more harmonics
and arc-suppression coil can not compensate for harmonic grounding currents.This will cause harmonic residual grounding current exceed the standard value
compensation effects be affected.It needs more attention to this question.
