The presence of defects in the insulating wall of high voltage capacitors can cause early deterioration of the insulating system and can lead to the degradation of electrical properties. The presence of partial discharges (PD) is considered to be one of the main causes of initiation of the degradation of the insulating wall. Accordingly, PD measurement is used …
Key learnings: Capacitor Transient Response Definition: The transient response of a capacitor is the period during which it charges or discharges, changing its voltage and current over time. Charging Behavior: When a voltage is applied, the capacitor charges, with the current starting high and decreasing to zero as the voltage across it …
