Abstract
Incendiary brush discharges can occur when a large or
grounded conductor approaches a charged insulator in the
presence of flammable atmosphere. The probability of
ignition of these discharges is essential to risk
assessment in process industry. It is known that even if
the total energy released in the discharge exceeds the
minimum ignition energy (MIE), there may not be an
ignition [1]. In a companion paper in this conference, we
have reported simultaneous measurements of ignition and
discharge current waveforms for brush discharges in an
ethylene-air mixture in ignition tests based on an IEC
standard test method [2]. In this paper we show that the
resistance of the electrostatic discharge measurement
system can have an effect on the peak discharge current
signatures and charge transferred in the brush discharge
from an insulating surface. The resistance of the
discharge probe seems to affect the peak current value,
but also to lesser extent the amount of charge
transferred in the discharge.
