FMECA development in PLN TRANS-JBTB

A Reliable power transmission is one of the asset management objective of PLN Trans-JBTB as a Power Transmission Utility. This objective is measured by frequency and duration outages of transmission line and transformer (TLOD, TROD, TLOF, and TROF) that occur every year. In order to improve reliability, fault history data in 2014–2017 is evaluated using FMECA and risk matrix to obtain a failure mode with the most seriousness effect. This paper discussed about developing FMECA in PLN Trans-JBTB as a method for decision making and prioritizing to achieve a reliable power transmission. Risk Priority Number (RPN) is then calculated to get the top 5 failure mode with the highest RPN value.
