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?

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.

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

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

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.

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

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

Recently, I cleared my JP Morgan coding round. Next, I received mail for a video interview. What kind of questions are asked in this round? How do I prepare myself?

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

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

Edit 2024–10.

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

“ 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”

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

The other is “what does a “fuse” do?”

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

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

Barnstars:

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.

What is lightning?

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

How do people in your country say "you're welcome" in their native language(s)? Is it a commonly known phrase or do most people just reply with "no problem"?

Here is a simplified AC power diagram.

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

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

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

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

What does a fuse do?

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

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.

He then describes the function of a fuse.

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

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

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.

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

There are two important concepts here.

First Sentence:

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

In schematic diagrams this is the symbol for a fuse:

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

He then describes Rainy Season and Lightning.

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.

But it can get overloaded, and no longer works.

a photo is worth a thousand words.

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

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

This one hit behind the barn.

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

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

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

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

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

At least they know the answer if they wanted it.

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

I post the exact comment here.

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

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

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

This device then solves the entire problem.

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

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

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

He then asserts :

Upvotes:

what exactly is a ‘surge’ protector?

(Dc diagram shown, AC is similar).

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

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

A circuit breaker is similar, but is resettable.

There are three different concepts here that are getting confused.

This is 'the assistant's answer'
