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?

There are two important concepts here.

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

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

This device then solves the entire problem.

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

One

Why did you put a guy’s dick in your mouth the first time?

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

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

Upvotes:

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

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

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.

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

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

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.

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

“ 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”

so, what happens?

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

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

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

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

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

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

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

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

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.

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

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

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.

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

There are three different concepts here that are getting confused.

He then asserts :

The other is “what does a “fuse” do?”

a photo is worth a thousand words.

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

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

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

But it can get overloaded, and no longer works.

What is lightning?

What does a fuse do?

Barnstars:

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

what exactly is a ‘surge’ protector?

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

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

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

He then describes the function of a fuse.

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.

In schematic diagrams this is the symbol for a fuse:

Here is a simplified AC power diagram.

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

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

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

This one hit behind the barn.

I post the exact comment here.
