Products/Services for fault mode
Ground fault relays protect electrical equipment from ground faults. A ground fault is an unintentional current path between a current-carrying conductor and a grounded surface. Search by Specification | Learn More
Fault detectors and fault recorders are electric power instruments that detect and/or record electrical faults that may happen in power lines. A fault recorder keeps a log about the time, location, intensity of the fault. Learn More
Fiber optic fault locators shine red laser light through jacketed fibers to identify breaks, bends, faulty connectors, splices and other causes of signal loss. Search by Specification | Learn More
Failure mode and effects analysis (FMEA) software is used to track trends, generate statistics such as mean time between failure (MTBF), and determine the root causes of field failures (usually for products covered by a manufacturer’s warranty). Learn More
Switch mode transformers (switching transformers) are used mainly in switching power supplies and DC-DC converters. They provide a storage element for transferring energy from input to output in discrete packets as required in switching power supplies, regulators and converters.
