This paper demonstrates the feasibility of an interactive distributed measurement system having the capability of wireless triggering and time synchronisation for the purpose of detection, measurement and location of disturbances from very large electrical systems. System design, laboratory testing and preliminary site trials are discussed. Examples of how the system might be used are included. The first example relates to railway track circuit monitoring; the 2nd example relates to multi ended PD monitoring for insulated power cables; third example relates to radiometric partial discharge monitoring in substations and the last example relates to power quality monitoring and phasor measurements.
