Abstract
To locate a shunt, the shunt includes an RF transmitter configured to wirelessly transmit an identifier of the shunt such as the configured shunt frequency. The shunt may include switches or memory locations that may be configured by an installer to correspond to the configured shunt frequency. Other embodiments employ switches or sensors influenced by jumpers installed in the shunt to configure the frequency of the shunt. A portable device receives a transmission including the identifier and displays it along with an indication of the received signal strength of the transmission, and maintenance personnel move the portable device along the track to locate the highest received signal strength, which indicates the location of the shunt. The shunt may also include a test circuit that may be configurable to generate a test frequency, determine a parameter indicative of shunt performance, and output a signal based on the parameter.
