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 device then solves the entire problem.

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

Here is a simplified AC power diagram.

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

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

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

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

He then describes the function of a fuse.

“ 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”

Upvotes:

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

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 “.

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.

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

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

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

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

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

To those people in the world who have access to universal healthcare, what experiences could you share with Americans in order for us to understand how it affects your life (positively or negatively)?

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

He then asserts :

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

so, what happens?

This one hit behind the barn.

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

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

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

One

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

But it can get overloaded, and no longer works.

A circuit breaker is similar, but is resettable.

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

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

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

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.

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.

(Dc diagram shown, AC is similar).

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

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.

2024–10–14 [Omar Gharbi Omar Gharbi ]

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

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

The other is “what does a “fuse” do?”

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

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

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

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

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

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

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

In schematic diagrams this is the symbol for a fuse:

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

At least they know the answer if they wanted it.

eight

There are two important concepts here.

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

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

What does a fuse do?

what exactly is a ‘surge’ protector?

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

This is 'the assistant's answer'

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.

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

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.

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

He then describes Rainy Season and Lightning.

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