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?

2024–10–16 [ OO OLAOYE OYEBODE ]

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

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

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

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

What is the reason behind people believing in the concept of causation, even though it cannot be proven or deemed necessary for everything to exist?

There are two important concepts here.

There are three different concepts here that are getting confused.

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

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

He then describes the function of a fuse.

Is Claude AI better than ChatGPT for Alexa?

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

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.

But it can get overloaded, and no longer works.

What does a fuse do?

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

so, what happens?

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

What are some tips for keeping a durag on for a longer period of time?

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

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

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

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

Edit 2024–10.

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.

What is the most offensive thing someone has ever asked you?

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

“ 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”

A circuit breaker is similar, but is resettable.

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.

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

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

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

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

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.

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 where the MOV conducts again, and dissipated the energy.

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

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

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

what exactly is a ‘surge’ protector?

2024–09–27 [ Mohan Rajaratnam Mohan Rajaratnam ] . Thinks you can get free electricity from nothing : Mohan Rajaratnam's answer to Is it possible to generate free electricity at home using a magnet or other low-cost methods? If so, how does it work?

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

I post the exact comment here.

First Sentence:

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

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

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

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

He then describes Rainy Season and Lightning.

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.

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

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

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.

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

Here is a simplified AC power diagram.

At least they know the answer if they wanted it.

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

Upvotes:

This one hit behind the barn.

The other is “what does a “fuse” do?”

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

In schematic diagrams this is the symbol for a fuse:

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

This is 'the assistant's answer'

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