Caution: the installation devices for protection against power surges with varistors, diodes and other components between signal and/or power supply conductors and the protection earth reduces the isolation voltage approximately the value breakdown the discharger used. The suppresser diodes have response time ns) which much lower than that the varistors (approximately ns) and lower and more accurate response voltage, although compared varistors they withstand lower discharge currents.. less destructive than differential mode interference. ifferential mode interference (diagram 6): generates strong difference potential between the two conductors signal power supply unit and the reference earth.
