DFA100 DFA100 Dielectric Fault Analyzer The DFA100, Dielectric Fault Analyzer, is a handheld and battery powered instrument used for monitoring acoustic emissions. The acoustic emission diagnostic technique is a nonintrusive in-service test used for monitoring acoustic signals produced by partial discharge and loose components. The DFA100 is specifically designed to detect faults in grounded SF6 gas-insulated systems, such as SF6 filled dead tank circuit breakers. The DFA can also be applied to grounded oil filled instrument transformers. The DFA100 instrument can be directly applied to any grounded component that is associated with the SF6 filled apparatus under test. During acoustic emission measurement, the DFA100 processes the results and determines the fault. The DFA100 instrument has the ability to differentiate between PD, particles, and mechanical defects. DFA100 Application: • Identify and Locate – PD, particles, and mechanical defects. • ondition based monitoring of GIS, SF6 filled dead tank C breakers, instrument transformers, during commissioning and while in-service. • he results can be used by itself or in conjunction with T other in-service test results for assisting in decision making process. DFA100 Benefits: • apid Results – the DFA100 is quick and easy to R configure, giving results in seconds. • eliability and Ease of Use – the DFA100 produces R high quality results with high repeatability allowing for rapid and reliable decision making. • attery operated – the DFA100 is a stand-alone handB held instrument, which can operate up to 4 hours on one charge. • ireless Synchronization – the DFA100 utilizing a wireW less synchronization module for timing PD and mechanical activity against the power system frequency. • electable Settings – the DFA100 provides recomS meded setting for testing both SF6 filled and oil filled equipment. • ugged and Reliable – the DFA100 is an instrument R with outstanding durability for field use. • imple User-friendly PC interface – a simple interface S allows the test results to be uploaded to a PC. Previous data and nameplate configurations can also be downloaded to the DFA100.
