Abstract
Transformers are very important and costly apparatus in power system especially in high voltage. Without them, utility companies would not be able to transmit and distribute electricity generated at remote power stations. Great care to be exercised to see that the transformers are not damaged. Oil is used as an insulator and coolant in transformers and by monitoring its condition the transformer’s overall health is determined. Temporary failures due to overvoltage are reinsulated quickly by liquid flow to the affected area. Since years ago, petroleum-based mineral oil has been used to serve the dual purpose of insulation and heat dissipation. However, this petroleum will be come to an end because it is a non-renewable source. Most importantly is the inability of mineral and petroleum oils to comply with environmental regulation laws. Therefore, mixture of RBD coconut oil and mineral oil will be used in this project as alternative liquid insulation. According to previous research, natural vegetable oils have been found to meet the specifications IEC 60296. Their biodegradability makes them safe for use in densely populated areas and close to waterways. This also makes them to be environmentally compliant and avoidance of sanctions from regulatory agencies. Since they are
from renewable sources, their production and utilization is simple and cost effective. Overall, this can ensure sustainable development.
