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.”

But it can get overloaded, and no longer works.

“ 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.

At least they know the answer if they wanted it.

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

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.

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.

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

What does a fuse do?

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

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

In schematic diagrams this is the symbol for a fuse:

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

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.

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

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.

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.

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

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

First Sentence:

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

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

New study maps psychological pathway from childhood abuse to adolescent addiction - PsyPost

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

(Dc diagram shown, AC is similar).

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

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

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

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

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

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

There are three different concepts here that are getting confused.

eight

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

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

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

The other is “what does a “fuse” do?”

There are two important concepts here.

This is 'the assistant's answer'

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

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

He then describes Rainy Season and Lightning.

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

so, what happens?

He then asserts :

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

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

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

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

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

what exactly is a ‘surge’ protector?

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

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

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

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 the function of a fuse.
