Let's take a look at some electrically focused hypothetical examples to further explain this method. Now, if the fault magnitude is really high, a different methodology is required: engineers have to use active or passive redundancies to enhance fault tolerance on their devices. There is an indirect correlation between the mechanical breaking of rotor bars and the fluctuations in the stator current. Fault detection is the process of discovering the presence of a fault in any equipment before it manifests itself in the form of a breakdown. 6 What to do if there is no fault in a safety relay? Nevertheless, the Fault Detection and Diagnostics algorithm for any equipment should contain at least the four key processes listed below (these can constitute a nonlinear process as well, provided that some steps happen at the same time): We need to discuss each element in more detail to really understand how fault detection and diagnostics work.
