Is the question then , "why buy a surge supressor, if the fuse alone protects the electronic circuits from a lightning bolt?".

At one ohm, the resistor has a maximum of 1 watt power.

This device then solves the entire problem.

These devices are installed between the “hot” and “neutral” and protective ground.

The MOV will conduct when the voltage exceeds 50% of line voltage.

Lightning arrestor is a spark-gap device, and can be installed anywhere. What is important, is that the wire is thick enough to withstand the lightning bolt and conduct the energy away from the building.

Would individual surge supressors have save this equipment? most likely, since the surge supressor would take the jolt instead of the electronic components.

Can the fuse protect the electronic devices from lightning instead of a surge protector.

the problem then depends on "how fast does the fuse operate?".

He then describes the function of a fuse.

OK, this is Mohan Rajaratnam’s definition of a Surge suppressor.

P = e* I, so since I is 16 amps, then the voltage dropped is 1/16 volt or 0.0650 volts.

This is where the MOV conducts again, and dissipated the energy.

There are three different concepts here that are getting confused.

But… the neutral is now “floating” because of the 1 ohm resistance.

So combined with a device called a MOV or Metal-oxide-resistor, then forms the 3rd part of a “surge suppressor “.

There is no harm in having the surge suppressor along with the fuse in the circuit. The fuse will not open up until the current melts the link. This will take time, and in the interim, that jolt will get transmitted into the power supplies.

but I think this circuit , shows a few more pieces.

He then describes Rainy Season and Lightning.

An AC voltage/ current source, and an ac inductive load.

What are the easiest stores for shoplifting?

so, what happens?

This is a high voltage low current spike that comes down the line because of the power poles being struck, and the voltage suppressors activating on the primary side of the transformer.

But it can get overloaded, and no longer works.

What is lightning?

If the nominal power is 4,000 watts then the current at 230volts is 16 amps.

This is where this question deviates from being a 'generic' question, and becomes more specific.

“ A surge suppressor is the one which is connected at the input supply so that when there is a sudden change voltage it bypasses thereby protecting the (circuit) and electronic components”

Edit 2024–10.

So, the voltage could go up to 500 volts, and the fuse will not open up.

A circuit breaker is similar, but is resettable.

This is 'the assistant's answer'

(Dc diagram shown, AC is similar).

At the secondary, it is 1000 times less.)turns ratio). If it gets hit with a 100,000 volt bolt of lightning then the voltage arrestors conduct and clamp the voltage down to line voltage, ( but a small amount leaks down the line). This is the problem.

(There is no concept of polarity, in the loop because the current changes direction 100 to 120 times a second (power frequency).

This is a photo where a lightning bolt took out a home's complete mains distribution box, and a lot of electronic gear as well.

A fuse is a non-resetable over current circuit protector.

so, the loop of wire then, when put together with another loop reduces the ‘noise’ on a power line.

I post the exact comment here.

And this is the problem alone. Is the power supply in the equipmemt designed with a lightning strike in mind? Some yes, others, no.

One is “what exactly is in a ‘surge protector’ ? ”

These are simplified answers to the original question, and does not change anything I wrote above.

The bolt then partially travels down the line to your home.

It seems Mohan does not understand the difference between a comment and an Answer.

Now when you have a certain ac resistance, then a current flows in a loop.

what exactly is a ‘surge’ protector?

“ … to protect building, lightning arrestor, is provided above building and directly connected to earth.”

When the current is 200% of the rated value , it will “go open” (the link metal melts) and protect the device.

At least they know the answer if they wanted it.

In schematic diagrams this is the symbol for a fuse:

Once the voltage goes over 0.0650 volts, then this fact can be used to amplify the difference, and turn the circuit breaker off , furthur down the line. Essentially that is what a RCD/GFCI does, it compares the incoming current, to the outgoing current, and if the difference between the two currents is over 5mA, then it trips the circuit breaker.

Fuses, on their own, then operate much slower than the MOV variable resistance, during the lightning strike.

The other is “what does a “fuse” do?”

“ A fuse is a device which protects the (circuit) against overload and short circuit.”

There are two important concepts here.

but this device (an Inductor) … impedes the rapid changes in the current.

What does a fuse do?

It also is a device that limits the change in current flow.

For this case there are devices called Metal oxide varistors (MOV).

But during the surge, the fuse will not blow if it is a longer duration and lower value )10 to 50%).

The third is lightning and “how it gets conducted into a home.”

Because the load is inductive, the current lags the voltage.(by a bit).

So, it’s possible that these devices from Trip Lite have addition suppression devices, these ones seem to be sturdy.

Mohan forgets that a fuse is a one-time device, and needs to be replaced if it is tripped.
