  • Decomposition Characteristics of SF6 and Partial Discharge

    The experimental wiring of SF6 decomposition under negative DC-PD is illustrated in Figure1. A voltage regulator (T1: 0–380 V) and a testing transformer (T2: 50 kVA/100 kV) provide the AC high voltage (AC-HV). The AC-HV is converted into DC testing voltage by using a half-wave rectifier circuit,
