... equipment. This is usually a function of stray capacitance coupling to earth which depends critically on the mechanical layout of the circuit and the primary-to-secondary capacitance of the mains transformer, and can easily exceed 1000pF. The attenuation offered by the potential divider effect of CY may be no more than 15 – 20 dB. The common ...

... Figure 4.a shows the output voltage of the generator during operation of the apparatus. The voltage is submitted HV to fast fluctuations due to the discharge of condensers when Transformer capturing insects, and their charge which is carried out very quickly (some microseconds). Figure 4.b shows an increasing zoom of voltage fluctuation around the average ...
