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?

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

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.

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

What would it take for you to consider yourself a "Swiftie" like Flavor Flav?

What does a fuse do?

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

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

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

He then asserts :

Are narcissists happy people generally?

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

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

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

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

Why do atheists love to preach against Abrahamic religions and mock God? Even if they do not fear the eternal fire of hell, pious Muslims will certainly not leave them alone and will take brutal revenge until they surrender and repent of their sins.

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

This is 'the assistant's answer'

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

How do people break a narcissist man's ego?

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.

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

“ 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.

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

There are two important concepts here.

He then describes Rainy Season and Lightning.

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

Why did it take seven days for troops with helicopters, equipment, supplies, food, and water to be dispatched to southeast storm zones?

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

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

There are three different concepts here that are getting confused.

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

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

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

Liberals, why don't you like Conservatives?

what exactly is a ‘surge’ protector?

(Dc diagram shown, AC is similar).

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

How can I get over a break up?

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

In schematic diagrams this is the symbol for a fuse:

so, what happens?

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

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.

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

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

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

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

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

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

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

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

The other is “what does a “fuse” do?”

But it can get overloaded, and no longer works.

Upvotes:

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

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

This device then solves the entire 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.

I post the exact comment here.

A fuse is a non-resetable over current circuit 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.

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

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

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.

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.

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

Here is a simplified AC power diagram.

What is lightning?

A circuit breaker is similar, but is resettable.

[old diagram got deleted by accident]

At least they know the answer if they wanted it.

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

He then describes the function of a fuse.
