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

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

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.

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

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

But it can get overloaded, and no longer works.

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

What is lightning?

a photo is worth a thousand words.

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

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.

Why is my ex mad I moved on when he dumped me?

so, what happens?

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

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

He then asserts :

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

Which is the first MV you watched in Stray Kids?

what exactly is a ‘surge’ protector?

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.

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

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

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.

There are three different concepts here that are getting confused.

What does it mean when someone leaves something in your house, your room to be exact, and when you tell them, they say they left it there on purpose?

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

The other is “what does a “fuse” do?”

A circuit breaker is similar, but is resettable.

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

Here is a simplified AC power diagram.

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

I post the exact comment here.

Barnstars:

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

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

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

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.

First Sentence:

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

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

This device then solves the entire problem.

There are two important concepts here.

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

“ 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”

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

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

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

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

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

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

(Dc diagram shown, AC is similar).

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

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.

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.

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

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

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

What does a fuse do?

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

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

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

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

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.

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.
