Feasibility Test of Transformer Insulating Oil Lifetime Based on Breakdown Voltage (bdv) and Furan Analysis

Abstract

Optimization of transformer performance in distributing electrical energy is determining by transformer insulating oil
quality. Insulating oil temperature increases with the great of transformer workload released during the distribution
of electric power to consumers. Then, it will be affected to the breakdown voltage (BDV) value and oil quality which
can even lead to the insulating oil failure. This research is carried out by taking a sampling of new deck oil and used
oil at different temperatures. Then insulating oil is tested by using BDV test and Dissolved Gas Analysis (DGA) to
determining furan value and workability of insulating oil lifetime. Thus, this research expected to identify the feasibility
of transformer insulating oil lifetime based on breakdown voltage and furan value.
