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

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

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

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.

He then describes Rainy Season and Lightning.

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.

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

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

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

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.

The other is “what does a “fuse” do?”

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

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

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

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

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.

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

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

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

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

There are two important concepts here.

What is one thing nice you did for someone today or something they did for you?

what exactly is a ‘surge’ protector?

so, what happens?

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

What are some of the craziest laws around the world?

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

What is lightning?

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

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

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

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

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

Barnstars:

He then asserts :

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

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

He then describes the function of a fuse.

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

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

One

At least they know the answer if they wanted it.

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

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.

Upvotes:

But it can get overloaded, and no longer works.

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

[old diagram got deleted by accident]

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

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

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.

I post the exact comment here.

Edit 2024–10.

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

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.

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

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

What does a fuse do?

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

Here is a simplified AC power diagram.

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.

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

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

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

[image of Common-mode choke]

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

There are three different concepts here that are getting confused.

First Sentence:

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

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