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?

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

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

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

This device then solves the entire problem.

He then asserts :

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

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

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.

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

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

This couple paid $19M for 2 Jersey Shore houses. Then they demolished them. - NJ.com

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

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.

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

What does it mean if you dream your dad died?

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.

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

There are two important concepts here.

There was this one weird Bollywood movie that was released in the 2000s. Amitabh Bachchan was starring with another actress and the story was about how the old guy (Amitabh Bachchan) fell in love with the young woman. What is the name of this movie?

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

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

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

so, what happens?

It’s been over a month since I stopped taking sertraline but why do I still feel side effects like brain zaps and anxiety mood changes? The root cause of anxiety it’s your thinking and I perfectly master that better than before so it’s hard lately.

He then describes the function of a fuse.

First Sentence:

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

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

Can you tell me a depressing story?

What is lightning?

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

He then describes Rainy Season and Lightning.

Why do I get spun and then want big fat cocks to suck?

“ 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”

There are three different concepts here that are getting confused.

2024–10–14 [Omar Gharbi Omar Gharbi ]

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

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.

what exactly is a ‘surge’ protector?

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

[image of Common-mode choke]

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

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

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

Upvotes:

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

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

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

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

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

This is 'the assistant's answer'

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

What does a fuse do?

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

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

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.

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

At least they know the answer if they wanted it.

The other is “what does a “fuse” do?”

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

But it can get overloaded, and no longer works.

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

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

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 one hit behind the barn.

In schematic diagrams this is the symbol for a fuse:

Here is a simplified AC power diagram.

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

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.

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

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

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