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?

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.

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

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

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 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 circuit breaker is similar, but is resettable.

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

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

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

He then asserts :

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

But it can get overloaded, and no longer works.

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

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

Upvotes:

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

There are two important concepts here.

Why do some people enjoy being dominated?

“ 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”

One

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

The other is “what does a “fuse” do?”

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

What does a fuse do?

What questions will be asked by the executive director of JP Morgan for 6 years of experience in Java? The technical rounds are already cleared.

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

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

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

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

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.

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

There are three different concepts here that are getting confused.

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

This device then solves the entire problem.

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

so, what happens?

He then describes Rainy Season and Lightning.

[image of Common-mode choke]

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 where the MOV conducts again, and dissipated the energy.

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

This is 'the assistant's answer'

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

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

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

a photo is worth a thousand words.

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

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

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

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

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

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.

Here is a simplified AC power diagram.

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

He then describes the function of a fuse.

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

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

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

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.

What is lightning?

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

Barnstars:

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