Some discharging effectiveness was found in the oil tank system equipped with 100 or 200 mesh stainless screen fixed on top of the diffuser at the oil inlet. To study the discharging mechanism in detail, the potential distribution along the axis of the cylindrical oil tank, the earth current in each part of the oil-flow system, and surface potential of the oil tank were measured.
The temperature curves of dc current on liquid unsaturated polyester (UP) resins diluted by various amounts of styrene exibit several straight-line segments. From this the activation energies, glass and liquid-like transition temperatures have been evaluated. The transitions have been conformed by thermally stimulated discharge (TSD) measurements. The current intensity and transitions have been varied...
Trichlorotrifluoroethane (C2Cl3F3) is a stable molecule up to a temperature of 700°C. Under internal arc stress C2Cl3F3 was decomposed and Phosgene and other products were produced. The amount of produced Phosgene depends on the fed in energy per unit of gas mass and the presence of Oxygen. At the ignition of an arc in liquid C2Cl3F3 a shock-wave with amplitudes of up to 1 MPa occurs dependent on...
Photoconductivity induced by 347 nm light pulses in TMPD solution in liquid methylcyclohexane is measured. The unusual current kinetics has been found at T < 200 K when the light pulse duration was less or about the time taken for separation of initial electron-ion pairs. The kinetics is associated with the current of geminate electrons and has been shown to be consistent with predictions of the...
Measurements of the temporal variation of voltage and current in the spark discharge of liquid n-hexane were carried out. A dc-voltage, which increased linearly in time, was applied to a test cell with tip-plane electrode geometry. By careful mechanical design of the test cell a defined wave impedance of the whole experimental set-up was realized. A capacitive voltage divider was integrated into the...
With the charging geometry number 4 /1/ we got currents figured out (Fig. 2) in dependence of the volume flow V̇ (cm3/s) of the insulating liquid. 133 cm3/s is corresponding to a jet velocity of 100 m/s. The charging voltage UL is the parameter. If you figure up the charging current as a function of the charging field strength EL, a small band of measured values arises for the four charging geometries...
