The results of studies of the effect of the electrode material on the breakdown delay time of liquid dielectrics in the presence of oscillatory voltage pulses with amplitudes ranging from 70 to 150 kV are presented. The measurements were carried out on purified water, transformer oil and chemically pure n-hexane, using electrodes made of tungsten, steel, copper, aluminum and lead. It is shown that the breakdown delay time is affected mainly by the anode material. In particular, it is shown that the breakdown delay time of liquid dielectrics increases with an increase in the modulus of elasticity of the anode material. A mechanism which explains the effect of the anode on the ignition stage of a discharge in liquid dielectrics is proposed.
