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 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.

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

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

One

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

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

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

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?

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

He then describes Rainy Season and Lightning.

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

Does the interpretation of the Book of בראשית create in all generations the Chosen Cohen People יש מאין?

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

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

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

Can ringing in the ears be a sign of spiritual awakening?

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

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.

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

Can we trust the Bible when Constantine and the First Council of Nicaea took out many books of the Bible and altered existing translation by removing things?

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.

what exactly is a ‘surge’ protector?

This is 'the assistant's answer'

How do I stop having work crushes because I only keep getting disappointed almost every day as I keep seeing they don’t like me back and won’t ever ask me out?

This one hit behind the barn.

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

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

Why does it itch on my vulva, uterus, and sides of my vagina, but it doesn't itch inside the vagina?

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

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

At least they know the answer if they wanted it.

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

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

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

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

Why do men love to stink/being smelly?

(Dc diagram shown, AC is similar).

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

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

—— indirects on kuorans, irl and idols

so, what happens?

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.

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

How do flat Earthers explain the existence of other spherical planets?

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

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

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

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

There are two important concepts here.

A circuit breaker is similar, but is resettable.

a photo is worth a thousand words.

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

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

“ 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”

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

In schematic diagrams this is the symbol for a fuse:

Upvotes:

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

First Sentence:

The other is “what does a “fuse” do?”

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

What is lightning?

He then asserts :

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

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

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

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

There are three different concepts here that are getting confused.

What does a fuse do?

I post the exact comment here.

Here is a simplified AC power diagram.

But it can get overloaded, and no longer works.

Barnstars:

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.

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.

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

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.

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

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

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

This device then solves the entire problem.
