The purpose of this study is to establish an efficient maintenance plan based on relevant Condition Monitoring (CM) to reduce unplanned hazard failures due to presence of Corrosive Sulphur Deposition (CSD) in transformers. Many investigations have been reviewed to get sufficient data to understand and describe applied CM used in the maintenance plan. Problem addressed is: is the currently applied CM relevant for early detection the corrosion to reduce the probability of failures? The major result is the described gaps between the currently applied CM and selection of relevant CM suggested for providing specific indication of corrosion fault to approach cost-effective Condition Based Maintenance (CBM). The main conclusion: there is a need to develop a relevant CM technique to detect CSD at early stage and establishing a cost-effective CBM to reduce the negative impacts of failures such as industries economic loss and hazard effect on manpower life as well as environment.
