When you're doing an RCA to determine the source of a fault, you'll usually find 3 basic types of problems: physical causes; human causes; organizational causes; You can also do a root cause analysis if you want to drill down and find out exactly why a process or procedure is producing better-than-average results. Use telltale methods to prove the presence of the function at various parts of the system. Other faults may include improper operating voltage, mechanical failure of components, and excessive heating or corrosion. This piece of equipment has 10 safety switches that have to have their contacts in the closed position before the machine can operate. However, if you have a fault indication you are almost there.

Intermittent wiring faults occur because of dirty or poor connections, internally broken wiring and damaged wiring insulation. Maintenance of plant and equipment in engineering . Although it is difficult to achieve a sensor that can carry out self-diagnosis of all possible faults that might arise, it is often possible to make simple checks that detect many of the more common faults. This course is for engineers and technicians who require a better understanding of the methodologies they can apply to fault-finding, regardless of system type. Symmetrical faults. Chances are, you won't be an expert in repairing these devices, but you can take some practical steps to solve problems and help get your systems operational again in a timely manner. You will be expected to use a variety of fault location methods and procedures, such as gathering information from the person who reported the fault, using recognised fault finding techniques and diagnostic aids, measuring, inspecting and operating the equipment. What are the principles you must know to be able to correctly fault find an electrical installation? London, 04 Oct 2023, Members: 1,095 + VAT If a mechanic can easily see all of the historical work orders, inspections, and parts associated with a piece of equipment, it's easier to narrow the list of possible causes of the failure. How do you test for electrical faults? The same data can be used to establish a predictive maintenance strategy over the remaining life of the motor.
