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?

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

Can you explain the meaning of "mint condition" in relation to antiques or collectibles?

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

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

What was your biggest culture shock going to Europe?

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

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

Has anyone ever read The Holy Bible completely through? If so, what was your overall impression of it?

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

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

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

What are the bitter truths of life one should know?

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.

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.

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

Can cheating be a result of not truly loving or caring for someone, or is it sometimes just a spur of the moment decision?

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

In schematic diagrams this is the symbol for a fuse:

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

This device then solves the entire problem.

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

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

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.

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

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

Barnstars:

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

Is the Shia claim true that Imam Ali was born inside the Kaaba?

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

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

I post the exact comment here.

Have you experimented with bestiality?

What does a fuse do?

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

First Sentence:

The other is “what does a “fuse” do?”

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.

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

There are two important concepts here.

what exactly is a ‘surge’ protector?

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

Here is a simplified AC power diagram.

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

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

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

This is 'the assistant's answer'

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

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

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

He then describes Rainy Season and Lightning.

At least they know the answer if they wanted it.

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

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

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.

But it can get overloaded, and no longer works.

What is lightning?

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

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

He then describes the function of a fuse.

Upvotes:

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

This one hit behind the barn.

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).

so, what happens?

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

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

There are three different concepts here that are getting confused.

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

(Dc diagram shown, AC is similar).

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.

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

He then asserts :

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

2024–10–14 [Omar Gharbi Omar Gharbi ]

“ 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”

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.
