Faults can be classified as: Positive fault − sustained fault −Intermittent fault irregular, harder to find Tools for the Job Your standard of work is related to the quality and completeness of the tools available to you. It means that intelligent fault diagnosis methods still need the human labor to design the feature extraction algorithms, so the intelligent diagnosis methods seem to be not as intelligent as they are named. One mistake rookies make in troubleshooting is to start with the easiest place to measure, or the points in the flow they understand the best. ), any switches, relays, fuses, fusible links or circuit breakers related to that component, and the wiring and connectors which link the component to both the battery and the chassis (which is connected back to the battery to complete the circuit). What is half split fault finding technique? Half Split Technique of problem solving? Fault finding techniques - An introduction. When using the half split technique, the starting point is: at the output at the input: at a point mid way in the system: anywhere 3. These steps include collecting evidence, analyzing evidence, locating faults, determining and removing causes, rectifying faults and running a systems check. When things go wrong unexpectedly, you want to be sure you have the best solutions as quickly as possible. Fault location methods can be classified into different categories: Methods based on travelling waves in faulted line: in [6], authors present a travelling wave based fault location method, which was successfully applied on a transmission line, and extended to … I’m unclear if I’m suppose to use one of the functions and type in =SPLIT_HALF(numbers). Stay calm and you'll be sorted. Trace problems by going from plant to equipment item to sub-system. However, fault location using intelligent methods are challenging since they require training data for processing and are time consuming. This course is for engineers and technicians who require a better understanding of the methodologies they can apply to fault-finding… Thank you for your software. In IT we have frameworks for understanding how technology is layered on top of each other, which incidentally is also the best approach for finding faults (working from a bottom up approach). Hi all can anyone explain how to carry out fault finding on a ring main using the splitting the ring technique. Can anyone enlighten me please on this technique? Such an approach may work eventually (when every component has been changed!) Half Split Fault Finding Technique.
