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?

He then describes the function of a fuse.

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

In schematic diagrams this is the symbol for a fuse:

He then describes Rainy Season and Lightning.

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.

At least they know the answer if they wanted it.

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.

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

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

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

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

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 other is “what does a “fuse” do?”

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

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

What happens when you have paranoid schizophrenia?

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

Barnstars:

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 does a fuse do?

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.

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

Recently, I cleared my JP Morgan coding round. Next, I received mail for a video interview. What kind of questions are asked in this round? How do I prepare myself?

I post the exact comment here.

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

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

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

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

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

[old diagram got deleted by accident]

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.

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

First Sentence:

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

so, what happens?

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

But it can get overloaded, and no longer works.

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

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

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

“ 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”

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

What is lightning?

This is 'the assistant's answer'

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

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

Here is a simplified AC power diagram.

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

There are three different concepts here that are getting confused.

This device then solves the entire problem.

This one hit behind the barn.

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

2024–10–14 [Omar Gharbi Omar Gharbi ]

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.

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

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

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

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

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

He then asserts :

what exactly is a ‘surge’ protector?

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

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

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

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