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

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.

Is the saying "nice guys finish last" true? Can good intentions always lead to positive outcomes?

so, what happens?

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

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.

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

This one hit behind the barn.

Here is a simplified AC power diagram.

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

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

a photo is worth a thousand words.

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

What are the best examples of reverse psychology?

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.

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

This device then solves the entire problem.

Why did Cartman love Heidi purely with heart, her being the first one he ever did, but then one day Butters tells him that all women are manipulative and then he began to believe that she was a bad person and pretended to be a victim?

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

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

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

Is a man who enjoys anal sex considered a sissy? For those who think so, why can't they be thought of as someone who enjoys a variety of sexual pleasure?

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

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.

There are three different concepts here that are getting confused.

What happened to the American Russell Bentley from Texas that was fighting for the pro-Russian commies?

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.

But it can get overloaded, and no longer works.

There are two important concepts here.

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

In schematic diagrams this is the symbol for a fuse:

He then asserts :

The other is “what does a “fuse” do?”

“ 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”

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

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

What does a fuse do?

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.

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

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 is lightning?

what exactly is a ‘surge’ protector?

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

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

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

(Dc diagram shown, AC is similar).

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

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

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

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

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

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

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

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

He then describes Rainy Season and Lightning.

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

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

2024–10–10[John johnson John Johnson ]

A circuit breaker is similar, but is resettable.

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

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

I post the exact comment here.

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

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

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

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

He then describes the function of a fuse.

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.

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

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

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