One of the most common and difficult problems to solve in industrial power systems is the location and elimination of ground fault. Ground faults that occur in ungrounded and high resistance grounded systems do not draw enough current to trigger circuit breaker or fuse operation, making them difficult to localize.

Techniques currently used to track down faults are time consuming and cumbersome. A new approach developed for ground fault localization on ungrounded and high resistance grounded low voltage systems is described. The system consi ....etc

Real-time locating systems (RTLS)
Real-time locating systems (RTLS) is used to track and identify the location of objects in real time using nodes (badges/tags) attached to or embedded in objects and devices (readers) that receive the wireless signals from these tags to determine their locations.it is a system of finding the position of assets using active RFID tags. The tags broadcast a signal, which is received by three reader antennas. The time each signal is received is passed on to a software system that uses triangulation to calc ....etc

On standard mobile antenna systems (those NOT designated as no-ground-plane), it is imperative that the antenna mount be grounded to the vehicles chassis. Ungrounded mounts will cause high SWR readings and/or low output power readings. There are three common situations when the mount may be inadvertently affixed to an ungrounded fixture.

Swing-away SUV spare tire racks mounted on nylon bushings.
Luggage racks or RV ladders mounted with rubberized bushings.
Mirror arms on fiberglass trucks or motorhomes.
For proper performance the mount must be ....etc
