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 device then solves the entire problem.

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

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

Is there a possibility that we are living in a simulation and that there is a concept of rebirth?

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

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.

Have you ever been forced to dress like a girl?

“ 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”

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

A circuit breaker is similar, but is resettable.

Why do I want to give up on men?

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

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 one hit behind the barn.

What is the most unwatchable movie you have sat through?

What does a fuse do?

At least they know the answer if they wanted it.

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

How did the DMK alliance manage to keep the BJP out of Tamil Nadu politics all these years? Is the picture now changing in Tamil Nadu after the entry of Annamalai?

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

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

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

Do you love fat pussy?

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

I post the exact comment here.

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

Why do people who were very kind and loving once become cold-hearted?

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

What is the best/cute/funny/playful chat/conversation between brother and sister?

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

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

Here is a simplified AC power diagram.

Do foreign workers face discrimination in Canada?

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

This is 'the assistant's answer'

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

I’m a 25 year old teacher teaching at boys school & I have colleagues younger than me. I caught one of my students telling her he wanted her as his teacher instead & it hurt my feelings. They compliment her a lot. It makes me jealous. What do I do?

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

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

How do I develop the patience to read books?

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

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

If there is an abandoned house with no owner, can I live in it?

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

There are two important concepts here.

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

Can you write a poem or short story based on the first image that shows up on Pinterest?

He then describes Rainy Season and Lightning.

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.

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

Can trans people tell me what the criteria for a woman is excluding self identification (facts do not rely on self belief)?

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 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.

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

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

a photo is worth a thousand words.

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

In schematic diagrams this is the symbol for a fuse:

He then asserts :

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

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.

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

The other is “what does a “fuse” do?”

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.

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

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

Edit 2024–10.

What is lightning?

what exactly is a ‘surge’ protector?

2024–10–11 [Victor Olarewsju Victor Olarewaju ]

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

so, what happens?

But it can get overloaded, and no longer works.

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

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

He then describes the function of a fuse.

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

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.

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

First Sentence:

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

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

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

(Dc diagram shown, AC is similar).

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