Real-World Fault Finding Cases. This technique involves dividing the system into two halves and testing each half to identify which one contains the fault. The main goal of fault finding is to delay the repair process to save costs associated with immediate action. Additionally For example, a restriction to the movement of the motor, causing it to draw more load may well operate the Control fuse prior to any of the more sensitive devices, while a dead short across the coil to neutral would most lily cause the CB to trip before the 16A BS88 in the isolator (which is closer to the load). In mechanical engineering, it’s really important to quickly find and fix problems in machines and systems. I've now got onto the fault finding section, I've go to answer the following. Jun 17, 2020 · For example, if a doorbell does not ring when it should, it is only by means of a systematic approach that one determines that the bell itself is faulty.

If the cause of a fault is not removed, the fault will recur even though the fault has been rectified. Testing Capacitors & Motors4. Determination and Removal of the Cause. The article covers fault-finding control circuits, emphasizing the need for common sense, awareness, and logical approaches to diagnose faults in electrical systems. It discusses various causes of faults, symptoms, and their potential sources, highlighting the importance of observation, communication, and systematic testing techniques to identify and rectify issues efficiently. The slightly longer version is to use the ‘six steps’ approach, to make sure you’re not missing a trick. Fault finding, also known as diagnostic engineering, uses different methods to spot issues. There are too many faults that you may be given to list here but the types of fault can be: Short circuit; No continuity; Polarity; High resistance examples of their appropriate use: substitution replication p erformance and functional testing environment change he sequence of actions to be systematically followed when carrying out fault diagnosis where there are a wide range of causes or this is a new or unfamiliar fault. Also an intuitive approach can be used but must be accompanied by a deductive technique. Diagnosis of faults requires a logical and disciplined approach.
