so2 analysis for high voltages

2006-7-15The SO2 solubility in [hmim][Tf2N] is extremely high; at 25 &C, the mole fraction of SO2 approaches 0.9 near the SO2 saturation pressure of 3.44 bar. By contrast, the mole fraction of CO2 in this same IL under similar conditions is only 0.10.17,20 The solubility of N2 is sufficiently low that it is not measurable with our

    Moreover, capacitive voltage dividers are usually used for voltages above 100 kV in RMS value. The reason why is that resistive voltage dividers dissipate too much heat for high voltages, while ideal or near-ideal capacitors store the energy in the form of an electric field and release it in the circuit.
