Data recorded during faults in transmission network are used by control centre personnel to analyze the protection system and to decide on remedial actions that will restore normal network operation as fast as possible. The increasing number of installed digital fault recorders (DFRs) and other intelligent electronic devices (IEDs) in substations has resulted in a large number of fault records to be analyzed by the power system engineer. Manual analysis of these records is both time-consuming and complex and for these reasons, many records may not be examined and much of their potential value would be lost. Determining how to make effective analysis of these records is a challenge being faced by many power utilities. The main purpose of this paper is to propose enhancements to the manual investigation of faults and disturbances that currently are performed by engineers in the Indonesian power utilities. In this paper, a new software framework for Automated Fault Analysis is proposed based on Application Service Provider (ASP) technology, which has lately received special attention in the development of distributed systems. Demonstrations of the following services currently implemented in the ASP are presented: signal pre-processing, fault analysis and protection performance analysis. The fault scenario from South Sulawesi transmission system is investigated to test the feature of the services.
