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?

First Sentence:

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

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

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

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

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

Why is sin so sweet?

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

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

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

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

“ 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”

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

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.

Gun owners, imagine if an attacker comes to your home and takes your gun to use against you before you had the chance to pick it up. Would you regret owning a gun?

Upvotes:

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

But it can get overloaded, and no longer works.

Why do I have the impression that almost all questions about advertising the flat Earth theory come from people who don't believe in a flat Earth themselves and are just provoking?

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

This device then solves the entire problem.

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

The other is “what does a “fuse” do?”

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.

Have you ever been spanked in front of a group of people?

What does a fuse do?

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

What is lightning?

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

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

Edit 2024–10.

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

so, what happens?

At least they know the answer if they wanted it.

He then describes Rainy Season and Lightning.

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

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

There are three different concepts here that are getting confused.

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

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

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

This is 'the assistant's answer'

There are two important concepts here.

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

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.

It’s been three xxx five werks, and there has been no response to my follow on query on his Commment to my answer.

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

This one hit behind the barn.

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

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

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

what exactly is a ‘surge’ protector?

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.

A circuit breaker is similar, but is resettable.

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.

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.

2024–10–00 [ Ammar Mahdi ] Ammar Mahdi

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

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

(Dc diagram shown, AC is similar).

a photo is worth a thousand words.

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.

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