Further preferably, the capacitance of the capacitor is designed so that the capacitor for mains frequency, d. H. for a frequency of 50Hz or 60Hz, as high impedance as possible. This counteracts a compensation current across the screen.
- the capacitor has a capacitance smaller than 500nF, more preferably about 1nF-200nF. Most preferably, it has a capacity of 100 nF.
