Tags:,, is an essential skill for maintenance technicians in industrial, utility, or commercial settings. Locating faulty components, identifying power quality problems, and troubleshooting circuits are just a few of the issues the maintenance technician may be confronted with when repairing electrical malfunctions. The well-trained technician will be familiar with approaches that lead to resolving problems in the least amount of time, while using safe industry practices. Here’s some practical information for technicians and their managers about troubleshooting common electrical problems they may encounter in industrial settings. Analyzing Problems Before you begin to track down the cause of any electrical issue, it’s a good idea to refer to equipment or operation manuals and drawings. Aug 17, 2015 Top Ten Industrial Electrical Troubleshooting Tips. The world of electrical electronic equipment has changed so dramatically from its inception, that. Pilots: The FAA / NAA Dispatcher Written exam is very similar to the Airline Transport Pilot License (ATPL) written exam, so pilots can prepare for (or retake) the ATP while increasing their backup career options.

Are equipment history records available? If so, review them so you’ll be aware of recurring problems. Look for work orders, notes, and reports. Also, try to get an idea of how equipment works before you embark on troubleshooting. Once you begin your inspection of the equipment, look for signs of damage, including loose components, worn wires, or signs of impact. You should also examine wiring, printed circuit boards, and relay coils for signs of overheating. Use your senses: burnt insulation will give off a distinctive smell; listen to the equipment while it is operating to determine if something sounds off; and finally, check temperatures (with care!) to determine if components are hotter than they should be. Locating Faults Faults can occur for any number of reasons, so you will first need to observe the circuitry a section at a time, eliminating those parts of the circuit that seem to be working fine as your inspection progresses. A schematic diagram of the circuit can help you pinpoint the most likely areas where the fault is located. You might then make a list of possible causes. Among the most common causes of electrical faults are these: • Components that burn out or wear out easily, such as fuses, relay contacts, light bulbs, and mechanical switches are a major cause of malfunctions. Fuses, by the way, tend to burn out because there is a problem so don’t just change the fuse without also resolving the problem. • Motors, transformers, coils, or any devices with windings generate heat so can malfunction in time. • Connections may loosen, causing higher resistance and leading to overheating. Connections on vibrating equipment may be prone to coming loose. • Defective or incorrect wiring is a prime source of faults. Look for places where the insulation on the wires may be damaged, which can led to short circuits. Testing Observation alone will not always be enough to determine the cause of a fault so you may have to test it to pinpoint the source of the malfunction. A technician will need to master the use of many types of instruments for testing. Multimeters, for instance, measure AC and DC voltages, current, and resistance. There are also voltmeters, continuity testers, capacity testers, and many more, including advanced computerized equipment.
