Partial Discharge Phase Distribution of Palm Oil as Insulating Liquid
Abstract: Due to the low
biodegradability level of mineral oil and its susceptibility to the fire, palm
oil was proposed as alternative insulating liquid. This paper discusses partial
discharge (PD) in palm oil under sinusoidal voltages and the comparison with
mineral oil. PD was generated using a needle-plane electrode configuration
which is enable enhancing electric field at the needle tip. PD pulses were
detected using RC detector and they were measured using a Computer-based
partial discharge measurement system. The results showed that PD activities in
both oils are similar. The PD was initiated at the negative polarity of applied
voltage. The discharges took place in both polarity’s of applied voltage with
PD number was higher at negative one. Several discharges phenomena showed the
presence of space charge which changed electric field and governed PD
activities besides the main field introduced by voltage application.
