Abstract: In aspects, the present invention discloses a method for communicating with a plurality of field devices using a remote terminal unit. The plurality of field devices includes a first set of field devices and a second set of field devices capable of communicating using a first and second wireless communication protocols respectively. The method comprises scanning for a beacon message from a first field device, determining a corresponding wireless communication protocol associated from the first field device, identifying a first set of configuration blocks for communicating with the first field device based on a configuration schema file and the corresponding wireless communication protocol of the first field device, and building a protocol stack for use with a radio front end from the one or more radio front ends using the first set of configuration blocks, for communicating with the first field device from the plurality of field devices.

Abstract: A system and method for detecting location of fault in a cable receives disturbance data from first and second protection relays when one of the first protection relay and/or the second protection relay detects a fault in a section of the cable. The system extracts voltage and current data for each segment in the section using the disturbance data, cable parameters and length of each segment, and determines a fitness value for each segment in the section using the extracted voltage and current data. The system identifies a segment with a lowest fitness value from the fitness value determined for each segment in the section by comparing the fitness value of each segment with the fitness value of subsequent segments in the section and detects the segment with the lowest fitness value as fault location in the cable.

Abstract: A method for detecting the status of a mesh node in a wireless mesh network, wherein a gateway is building up a vector over time by combining active detection, passive detection and binary tests on anomaly metrics and wherein the status of the mesh node is regarded as misbehaving when the vector reaches a certain level.
