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?

[old diagram got deleted by accident]

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

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

Why is the mainstream media, traditionally liberal except for Fox, not reporting on Trump like he's a traditional candidate who has ideas, values, and a concern for the common good?

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

There are three different concepts here that are getting confused.

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

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

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

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

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

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.

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

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.

Here is a simplified AC power diagram.

“ 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”

What does a fuse do?

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

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

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.

He then describes the function of a fuse.

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.

I post the exact comment here.

At least they know the answer if they wanted it.

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

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

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

There are two important concepts here.

2024–10–11 [Bobby Sanchez Bobby Sanchez ].

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

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.

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

But it can get overloaded, and no longer works.

2024–10–10[John johnson John Johnson ]

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.

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

This one hit behind the barn.

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

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

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.

Upvotes:

The other is “what does a “fuse” do?”

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