Maintenance Strategy to Increase Power Transformer Reliability: Experience in Indonesia

The Java-Madura-Bali region of the Indonesian transmission grid includes about 1,299 power transformers or the equivalent of 109,347 MVA with variations in voltage level. To effectively implement predictive maintenance for these assets, the TSO, PLN, has developed an application taken from one type of maintenance based on predictive maintenance, namely condition-based maintenance. The system accommodates maintenance activities including visual, online and offline inspection as well as calculation of health index. This presentation offers an overview of methods related to implementation of maintenance on power transformers. Assessment includes a health/condition index, a life index and a risk index.
