    As I understand the arcing condition the "pre-arc" environment is characterized by a high potential difference and a minimal leakage current. During the "arc" the potential drops to near zero as the ion track completes the circuit and the current rises to high levels. In the "post-arc" environment the remaining potential is insufficient to sustain the arc and it dissipates.

    With some care, each of these regimes can be detected, sampled and analyzed in the time domain. Is that what you are after?
