TEMC-127-2009 1 Abstract--Measurements of impulsive noise in a 400/275/132

Summary: TEMC-127-2009 1
Abstract--Measurements of impulsive noise in a 400/275/132
kV electricity substation are presented. The measurements are
made with three antennas having overlapping bands covering the
range 100 MHz to 6 GHz. This range includes those bands
relevant to modern wireless local area network, and wireless
personal area network, technologies (e.g. IEEE 802.11a/b/g and
IEEE 802.15.1/4) which, if proved to be sufficiently robust in the
presence on impulsive noise, could play a useful role in substation
monitoring and control. Impulsive events are extracted from the
measured data using the wavelet packet transform and the
statistical distributions of pulse rate, pulse amplitude, pulse
duration, and pulse rise-time are presented. An unexpected
quasi-periodic component of the noise is observed.
Index Terms-- Bluetooth, electricity substations, impulsive
noise, noise amplitude distribution, partial discharge, wireless
local area network, ZigBee.
MPULSIVE noise has the potential to degrade the
performance and reliability of wireless communications
