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.

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

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

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

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

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

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

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

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

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.

In schematic diagrams this is the symbol for a fuse:

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

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

Is TikTok becoming a platform for soft porn?

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.

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

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

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 device then solves the entire problem.

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

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

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

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

This one hit behind the barn.

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

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

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

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

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

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.

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

so, what happens?

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.

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

I post the exact comment here.

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

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

what exactly is a ‘surge’ protector?

But it can get overloaded, and no longer works.

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

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

“ 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”

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

The other is “what does a “fuse” do?”

There are two important concepts here.

What does a fuse do?

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

There are three different concepts here that are getting confused.

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

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

He then describes the function of a fuse.

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

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