Field test study on XHG arc extinction , harmonic eliminating and line selection over voltage protective device
Yiping Fan · Ningxia Electric Power · 2007
XHG arc extinction, harmonic eliminating and line selection over voltage protective device is a late-model non-effectively neutral-point earthing system arc grounding over voltage protective device. For studying security, reliability and validity, carries out the related spot simulation test. The test result indicates that XHG arc extinction, harmonic eliminating and line selection over voltage protective device is able to choose out the line which arc grounding to be taken place within extremely short time, translates arc grounding into metallicity grounding, shortens the duration of arc grounding, reduces the damage of arc grounding over voltage, guarantees the system safety.
