A study to assess the impact of partial discharge on the performance of ZigBee equipment in high voltage electricity supply substations is described. The character of partial discharge and ZigBee technology are both briefly reviewed. A field trial system developed for deployment in a 400 kV air insulted substation is described in detail and some preliminary(More)
A measurement system for the characterisation of impulsive noise at frequencies above 700 MHz is presented. The system consists of a pair of ultra-wideband (UWB) quasi-TEM horn antennas, a digital storage oscilloscope and an external hard disk. The particular application of interest is the recording of partial discharge and radiation arising from(More)
A laboratory test to assess the impact of impulsive noise on the performance of WLAN equipment is described. The test is put in the context of a larger programme of work to assess the performance and reliability of wireless equipment subject to partial discharge noise in high voltage electricity supply substations. The character of partial discharge and(More)
