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?

He then describes Rainy Season and Lightning.

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

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

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.

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

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

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

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

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.

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

What does a fuse do?

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

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

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.

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

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

what exactly is a ‘surge’ protector?

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

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

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

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

(Dc diagram shown, AC is similar).

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.

There are three different concepts here that are getting confused.

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

How do you recognize when your mental health might need attention?

A circuit breaker is similar, but is resettable.

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

This device then solves the entire problem.

I’m a 25 year old teacher teaching at boys school & I have colleagues younger than me. I caught one of my students telling her he wanted her as his teacher instead & it hurt my feelings. They compliment her a lot. It makes me jealous. What do I do?

so, what happens?

Barnstars:

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

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

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

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

The other is “what does a “fuse” do?”

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.

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

2024–10–14 [Omar Gharbi Omar Gharbi ]

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

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

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.

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

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

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.

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.

At least they know the answer if they wanted it.

He then asserts :

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

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

He then describes the function of a fuse.

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

Here is a simplified AC power diagram.

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

I post the exact comment here.

In schematic diagrams this is the symbol for a fuse:
