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?

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

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

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

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

Why do we typically sing songs during Christmas instead of other holidays like Easter or Thanksgiving?

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.

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

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.

so, what happens?

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

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

When I buy a house, do I automatically own all items the previous owner failed to remove from the property?

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

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

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

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

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

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

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

But it can get overloaded, and no longer works.

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

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

There are three different concepts here that are getting confused.

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.

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

a photo is worth a thousand words.

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.

What does a fuse do?

2024–10–00 [ Ammar Mahdi ] Ammar Mahdi

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

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

He then asserts :

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

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

(Dc diagram shown, AC is similar).

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 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”

He then describes the function of a fuse.

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

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

A circuit breaker is similar, but is resettable.

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

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

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

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

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

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

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

There are two important concepts here.

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

What is lightning?

One

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

what exactly is a ‘surge’ protector?

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

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

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

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

Upvotes:

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.

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

The other is “what does a “fuse” do?”

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

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

In schematic diagrams this is the symbol for a fuse:

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