Abstract
In this study, the characteristics of electrostatic attenuation in plain shape glass filament sample (0.29 mm thickness, cross section of $\small{12.25cm^2}$, $\small{16cm^2}$, $\small{20.25cm^2}$) for insulator has been measured at temperature of $\small{5^{\circ}C{\sim}38^{\circ}C}$, humidity of 50%~90%. The results of this study are as follows. In case of samples that the cross section is $\small{12.25cm^2}$, $\small{16cm^2}$, $\small{20.25cm^2}$ at humidity of 50%~90%, it found that the electrification voltage of electrostatic increased with increasing temperature, with a return to decrease at $\small{20^{\circ}C}$. In case of samples that the cross section is $\small{12.25cm^2}$, $\small{16cm^2}$, $\small{20.25cm^2}$ at temperature of $\small{5^{\circ}C{\sim}38^{\circ}C}$, it found that the electrification voltage of electrostatic decreased with increasing humidity. In case of the sample at temperature of $\small{20^{\circ}C}$ and humidity of 65%, 75%, it found that the electrification voltage of electrostatic increased with increasing cross section. In case of the sample at humidity of 65% and cross section of $\small{12.25cm^2}$, the time that it takes to reduce electrification voltage of electrostatic in half decreased to 0.912s, 0.736s, 0.673s with increasing temperature to $\small{10^{\circ}C}$ $\small{20^{\circ}C}$, $\small{30^{\circ}C}$.
