Impulsive Noise Environment of High Voltage Electricity Transmission Substations and its Impact of the Performance of ZigBee
نویسندگان
چکیده
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 switching/fault transients in high-voltage electricity transmission substations. A preliminary assessment of the impact of such substation noise on the performance of ZigBee equipment is also described. The results, based on more than 200 MB of transmitted data, suggest that the substation electromagnetic environment has no significant adverse impact on performance.
