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?

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

Has a conversation with someone who holds opposing political views ever caused you to change your own beliefs?

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

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

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

My boyfriend always verbally abuse me and makes me cry. If I try to tell him how hurt I was, he says to me he loves me and can't hurt me but always abuse me. Why?

What does a fuse do?

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

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.”

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

This is 'the assistant's answer'

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.

What did your sister do to you that you can never forget?

He then asserts :

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

There are three different concepts here that are getting confused.

so, what happens?

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

what exactly is a ‘surge’ protector?

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

What are the best examples of reverse psychology?

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

Edit 2024–10.

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.

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

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

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

(Dc diagram shown, AC is similar).

One

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

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

This one hit behind the barn.

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.

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

In schematic diagrams this is the symbol for a fuse:

There are two important concepts here.

2024–10–14 [Omar Gharbi Omar Gharbi ]

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

This device then solves the entire problem.

a photo is worth a thousand words.

A circuit breaker is similar, but is resettable.

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

I post the exact comment here.

But it can get overloaded, and no longer works.

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

Here is a simplified AC power diagram.

Upvotes:

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

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

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.

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.

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

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

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

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

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

2024–10–10[John johnson John Johnson ]

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

“ 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”

2024–10–16 [ OO OLAOYE OYEBODE ]

He then describes the function of a fuse.

eight

The other is “what does a “fuse” do?”

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

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

He then describes Rainy Season and Lightning.

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

At least they know the answer if they wanted it.

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.

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

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

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.
