Mobile Low Voltage Fault Indicator

One of the most important requirements for an industrial enterprise is to ensure its continuous operating mode. Short circuits often put entire departments out of work. Finding and eliminating the short circuit takes a lot of time, as it is done manually. This procedure is greatly complicated if some of the electrical cables are laid in hard-to-reach places. This article discusses the principle of operation of the device, which makes it possible to significantly simplify the search for a connection on which a short circuit has occurred. The basic equations underlying the operating principle of the device are considered. It was found that the efficiency of the device depends solely on the coefficient of mutual inductance between the winding of the device and the cable under test. Computer simulation confirmed the results of analytical calculations. The main ways of increasing the mutual induction coefficient are considered. The use of a mobile low voltage fault indicator will reduce the economic losses of the enterprise.
