TV Components and Accessories.
Just as modern’s switch-mode power supplies compensate spontaneously
for voltage variations, they also naturally attenuate common-mode noise
(i.e. Voltage differences between the neutral and ground lines). Desktop
computers have five orders of magnitude of common-mode noise
attenuation built-in, from the EMI/RFI filter and the high frequency isolation
transformer in the power supply. Low-voltage, low-frequency ground
potential differences will not cause disruption or damage, because the
primary cause of disruption is coupling, which depends on frequency and
amplitude. Computers are inherently immune to common-mode
disturbances below a certain threshold, but problems occur when high-
energy incoming normal mode surges (i.e. differences between the hot and
neutral lines) are converted to common-mode surges by the action of shunt
surge suppressors. Surges originating from outside your building are
always normal mode, since neutral and safety ground lines are tied
together to an earth ground at the service entrance.
