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

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

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.

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.

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

What are some hard rock or heavy metal bands that are overrated?

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

This one hit behind the barn.

I post the exact comment here.

What was your wildest experience as a lesbian?

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

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

Here is a simplified AC power diagram.

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

When was the last time you had sex with someone much older than yourself?

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

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.

How does growing up in chaos affect a child as they become an adult?

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

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

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

If you believe in God, do you think God can save you from cancer?

This device then solves the entire problem.

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

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

He then describes the function of a fuse.

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

Why do many modern Hollywood films rely heavily on CGI and visual effects instead of actual sets? What is your opinion on this trend?

The other is “what does a “fuse” do?”

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

What does a fuse do?

What is the impact of being stereotyped as poor on an individual's life? How does it make them feel?

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

A circuit breaker is similar, but is resettable.

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

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

Who is the greatest light welterweight boxer of all time?

what exactly is a ‘surge’ protector?

This is 'the assistant's answer'

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

I'm straight, so why do I love watching guys cum?

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

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 bolt then partially travels down the line to your home.

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.

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

Barnstars:

Upvotes:

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

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

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

[old diagram got deleted by accident]

There are three different concepts here that are getting confused.

He then describes Rainy Season and Lightning.

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

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

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

“ 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”

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

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

[image of Common-mode choke]

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.

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

There are two important concepts here.

At least they know the answer if they wanted it.

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

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

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

In schematic diagrams this is the symbol for a fuse:

But it can get overloaded, and no longer works.

a photo is worth a thousand words.

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.

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