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?

What does a fuse do?

What is lightning?

How do people move on so quickly? I’m still sprung over someone I was dating and he found someone else so fast. I feel hurt because I’m still head over heels over him while he’s out enjoying his life with someone new

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

He then describes Rainy Season and Lightning.

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.

Why do flat earthers exist?

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

There are three different concepts here that are getting confused.

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.

(Dc diagram shown, AC is similar).

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.

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

He then asserts :

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

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

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

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

But it can get overloaded, and no longer works.

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

He then describes the function of a fuse.

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

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”

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

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

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

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

so, what happens?

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

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

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

This device then solves the entire problem.

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

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

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

Upvotes:

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.

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.

I post the exact comment here.

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

The other is “what does a “fuse” do?”

what exactly is a ‘surge’ protector?

There are two important concepts here.

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

First Sentence:

At least they know the answer if they wanted it.

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

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

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

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.

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

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

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

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

In schematic diagrams this is the symbol for a fuse:

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

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

Here is a simplified AC power diagram.

A circuit breaker is similar, but is resettable.

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

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

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.
