| Summary: | Insulation is one of the most important parts in a high voltage apparatus,
while insulator is a material that resists the flow of the electric current. Most of
the transformer used liquid insulating material where its function is to provide
electrical insulation and also act as a coolant to prevent overheating of the
transformer. Since years ago, petroleum-based mineral oil has been used as a
coolant and insulation purpose because of its high electric field strength, low
dielectric losses and good long-term performance. There are some reasons that
push the search of environmental friendly insulating oils. Conventional
transformer insulating materials are usually non-biodegradable. It can
contaminate soil and water when serious spill take place. This may disturb the
plantation and other lives. In future, this petroleum will be come to an end
because it is a non-renewable source. Therefore, this project has been carried out
to seek alternatives of vegetables oil that is more environmental friendly.
Refined, bleached and deodorized palm oil (RBDPO) has been recognized to be
the potential replacement for petroleum-based mineral oil. The main objective of
this project is to execute experimental study effect of ageing time and electrical
characteristic of Refined, Bleached and Deodorized Palm Oil (RBDPO) by using
partial discharge method. Another objective of this project is to make a
comparison on electrical properties between new insulating oil, RBDPO with
petroleum-based mineral oil. The result indicates the prospect of RBDPO to be
further processed to get better dielectric properties and meet all requirements to
be used as liquid insulating material. This is because RBDPO has a potential to
be a good liquid insulator because of its high breakdown voltage, low dissipation
factor and low capacitance when different ageing time were applied |
