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?

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

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

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

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

“ 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”

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

Were the 1980s as uptight and prudish as movies and TV shows make them out to be? When I think of 80s culture, I think about a very "icky" judgmental yuppie status quo time period.

At least they know the answer if they wanted it.

I post the exact comment here.

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

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

He then describes Rainy Season and Lightning.

This is 'the assistant's answer'

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

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

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

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

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.

What I have noticed is nearly every girl I try to connect with whom reject me are in their early 20s why is that the case?

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

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

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

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

Upvotes:

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

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

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.

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

Here is a simplified AC power diagram.

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

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

There are three different concepts here that are getting confused.

First Sentence:

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.

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 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.

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

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

The other is “what does a “fuse” do?”

Edit 2024–10.

What does a fuse do?

a photo is worth a thousand words.

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

so, what happens?

what exactly is a ‘surge’ protector?

One

He then describes the function of a fuse.

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.

He then asserts :

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

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

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

This device then solves the entire problem.

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

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

A circuit breaker is similar, but is resettable.

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

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.

(Dc diagram shown, AC is similar).

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

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

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

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

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

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

There are two important concepts here.

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

This one hit behind the barn.

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