Splet21. dec. 2024 · Voltage spike damage occurs more often in motors controlled by variable frequency drives. Troubleshooting the most typical winding problems of three phase electric motors. These problems are all caused by in-plant faults that require correction. A replacement motor can fail sometimes immediately if the in-plant problem isn’t corrected. An asymmetric or unbalanced fault does not affect each of the phases equally. Common types of asymmetric fault, and their causes: • line-to-line fault - a short circuit between lines, caused by ionization of air, or when lines come into physical contact, for example due to a broken insulator. In transmission line faults, roughly 5% - 10% are asymmetric line-to-line faults. taxe constructysSpletA ground fault is an inadvertent contact between an energized conductor and ground or a grounded equipment frame. The return path of the fault current is through the grounding system and any personnel or equipment that becomes part of that system. Ground faults are frequently the result of insulation breakdown. taxe coliving
