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?

so, what happens?

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

I post the exact comment here.

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.

“ 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”

Decade after decade, century after century the Middle East has been a disaster for anyone thinking peace can be achieved. Would it not be better to just leave the Middle East to its own devices and everyone else stay out of it all?

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

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

He then describes the function of a fuse.

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

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

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

This is 'the assistant's answer'

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

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

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

Upvotes:

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

Do Europeans typically set heating to higher temperatures in the winter compared to Canadians and Americans if the temperature at a given moment is similar?

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

There are two important concepts here.

Is the Chinese economy currently collapsing? If not, what could potentially cause it to collapse?

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

The other is “what does a “fuse” do?”

My boyfriend won’t tell me his past and it hurts me so I broke up with him what do I do?

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

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

Why can’t the British eat or drink anything unless they place a table cloth on the table first?

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

This device then solves the entire problem.

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

Can the right person make a narc want to change their ways? Is love that powerful? Has anyone seen this or experience it?

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

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

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

How come Jesus died on Friday and rose on Sunday? That's not 3 days and three nights.

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

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

What is lightning?

At least they know the answer if they wanted it.

In schematic diagrams this is the symbol for a fuse:

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

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

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

There are three different concepts here that are getting confused.

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.

He then asserts :

Here is a simplified AC power diagram.

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

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

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

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

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

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

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

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

What does a fuse do?

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

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

First Sentence:

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.

(Dc diagram shown, AC is similar).

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.

But it can get overloaded, and no longer works.

A circuit breaker is similar, but is resettable.

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

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

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

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.

Barnstars:

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.

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, 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%).
