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?

He then describes Rainy Season and Lightning.

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.

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

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

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

a photo is worth a thousand words.

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

The other is “what does a “fuse” do?”

I live in Massachusetts. Are there any resources here for people that are being harassed by voice to skull, etc.?

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.

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

One day, I happened to walk past where my crush was with friends. Then all of a sudden they start laughing, and someone maybe him, goes "freaking (my name) with her freaking hair!" Can anyone offer insights into this? We're in middle school.

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

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.

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

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

He then asserts :

At least they know the answer if they wanted it.

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

What is a common thought that keeps people up at night? Why do some people experience this?

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

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.

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

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

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

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

Why does it smell so bad? I noticed that when I move around my vagina has a stench. It’s usually a wet liquid, almost like pee. There’re little to no discharge and it doesn’t hurt or itch.

I post the exact comment here.

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.

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

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.

[old diagram got deleted by accident]

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

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

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

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

First Sentence:

Edit 2024–10.

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

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

A circuit breaker is similar, but is resettable.

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

[image of Common-mode choke]

What does a fuse do?

“ 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”

There are two important concepts here.

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

(Dc diagram shown, AC is similar).

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

Upvotes:

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

What is lightning?

This device then solves the entire problem.

This one hit behind the barn.

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

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

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

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.

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 “.

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.

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

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

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

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

In schematic diagrams this is the symbol for a fuse:

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

so, what happens?

But it can get overloaded, and no longer works.

He then describes the function of a fuse.

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.”

There are three different concepts here that are getting confused.

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