What exactly is the difference between a surge protector and a fuse? Can a fuse protect the electronic devices from lightning instead of surge protector?

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

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.

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

“ 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”

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.

what exactly is a ‘surge’ protector?

What would TERFs do if there weren't such a thing as being transgender? Who would be their target?

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

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

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

He then describes Rainy Season and Lightning.

He then asserts :

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

This is an electronic circuit designed to clamp voltages so that the Voltage Potential that appears at the outlet is never going to exceed the nominal value.

Why aren't F1 cars popular on the street?

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

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

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

But it can get overloaded, and no longer works.

A circuit breaker is similar, but is resettable.

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

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

What does a fuse do?

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

[old diagram got deleted by accident]

so, what happens?

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.

I can not sleep. what is the problem?

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

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.

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

Do all therapists specialize in one specific type of therapy, or are they trained in multiple types?

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

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

This one hit behind the barn.

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

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

One

(Dc diagram shown, AC is similar).

In schematic diagrams this is the symbol for a fuse:

He then describes the function of a fuse.

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

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

There are two important concepts here.

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

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

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

This is the picture of an electronic coil of wire wound around a core of magnetic material.

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.

This is 'the assistant's answer'

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

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

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

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

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

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

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

There are three different concepts here that are getting confused.

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

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

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

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

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.

This device then solves the entire problem.

I post the exact comment here.

a photo is worth a thousand words.

At least they know the answer if they wanted it.

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

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

The other is “what does a “fuse” do?”
