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?

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

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.

How can Democrats not feel hypocritical when they urge Trump not to be vengeful should be become president when the Democrats are trying to put Trump into prison?

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

Edit 2024–10.

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

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

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

A circuit breaker is similar, but is resettable.

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.

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

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

so, what happens?

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.

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

I post the exact comment here.

What should I do to stop being angered easily?

“ 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”

What's a band that is really popular that you don't like? Why?

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

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

What does a fuse do?

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

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

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

What is lightning?

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.

First Sentence:

What is your best gay fantasy?

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

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

This is 'the assistant's answer'

Here is a simplified AC power diagram.

There are three different concepts here that are getting confused.

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

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

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

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.

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.

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

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

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

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

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

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

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

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

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

At least they know the answer if they wanted it.

But it can get overloaded, and no longer works.

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

He then asserts :

There are two important concepts here.

The other is “what does a “fuse” do?”

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.

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

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

In schematic diagrams this is the symbol for a fuse:

what exactly is a ‘surge’ protector?

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

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

This device then solves the entire problem.

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.

He then describes the function of a fuse.

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

(Dc diagram shown, AC is similar).

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

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

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