Supplementary to EMI/RFI/EMC Immunity of an Equipment. Many
Installations are subject to Highly Disruptive Electrical Environment
not just EMI. Depending on the budget and the situation a solution has
to be found. Sometimes a CVT or an Isolation Transformer can do a lot of
Converting all Energy inputs to battery energy and having a
Isolated Synthetic Sine Supply may be an expensive but good solution.
Either way the devices that face the harsh environment have to be over
rated along with these protections. - delabs design Notes
Abstract-This study examines the design and construction of AC
Electronics load surge protection in order to carry electric surge load
arisen from faults in low voltage electricity system (single phase/220V)
by using the principle of electronics load clamping voltage during
induction period so that electric voltage could go through to safe load
and continue to work. The qualification of the designed device could
prevent both transient over voltage and voltage swell.
Mains Strip Board should have protection, The EMI RFI filter, Varistors
can help. Earthing and Lightning Arrestors should be good in the
The Blue ones are MOV Metal Oxide Varistors, sometimes they fail as a
short circuit, so better to use a fast blow fuse. Then you see Gas Tube
Arrestors that are even used in a Landline Terminal Box.
A Surge Arrester
is a device to protect electrical equipment from over-voltage
transients caused by external (lightning) or internal (switching)
events. Also called a surge protection device (SPD) or transient voltage
surge suppressor (TVSS),
Line-Filter - A
special class of capacitor is used in power-line (mains) filters. Line
filtering is a very tough application for a capacitor.
Achieving EMC for Dc-Dc Convertors - DC-DC
converters, whether they be an off the shelf brick design or a discrete
equivalent, are a source of EMI (Electromagnetic Interference). EMI is
unwanted electromagnetic energy that propagates by radiation and
conduction over system signal and power lines.
"The harnessing of electrical power to lighten mankind’s work-load is
only a little over a century old. During my own career, I have witnessed
many changes in equipment, work methods, industry organization, and
"All electrical systems are composed of the same basic equipment.
Experience has shown it is most economical to generate power in large
bulks, transmit it at very high voltage to minimize line losses, and
transform it to low voltages for safe feeding to individual customers in
