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?

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.

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

Why has Biden pulled ahead in battleground states and is now projected to win the 2024 presidency?

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

Edit 2024–10.

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

What are the strangest parts of The Bible?

But it can get overloaded, and no longer works.

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.

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.

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

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

Why do all the stupid people think Donald J. Trump is stupid?

There are three different concepts here that are getting confused.

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.

Why did my ex-narcissist move so fast with his new supply marriage engagement moving in, etc.?

This is 'the assistant's answer'

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

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

What would happen if Kakashi and Naruto switched places?

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.

How many wishes do people get on their birthday?

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.

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

This device then solves the entire problem.

“ 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”

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

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

What is one thing nice you did for someone today or something they did for you?

The other is “what does a “fuse” do?”

2024–10–16 [ OO OLAOYE OYEBODE ]

a photo is worth a thousand words.

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 I think this circuit , shows a few more pieces.

A circuit breaker is similar, but is resettable.

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

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

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

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

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

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

what exactly is a ‘surge’ protector?

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

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

Upvotes:

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

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

He then describes Rainy Season and Lightning.

Here is a simplified AC power diagram.

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

(Dc diagram shown, AC is similar).

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

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

Barnstars:

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

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

What is lightning?

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

He then asserts :

There are two important concepts here.

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

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

This one hit behind the barn.

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

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.

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

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

He then describes the function of a fuse.

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

2024–10–00 [ Ammar Mahdi ] Ammar Mahdi

What does a fuse do?

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

At least they know the answer if they wanted it.

so, what happens?

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