Diagnosis test of power cables using a resonant test system and analysis of partial discharge on site

On‐site partial discharge detection of power cables using a novel DAC technique supplied by a capacitor bank

“…The general components of a frequency-tuned resonant system are presented as following and the schematic is depicted in Fig. 1 [35]. The ACRF system is tuned into resonance when the output frequency of the frequency converter is equal to the natural frequency of the HV circuit, shown as…”
