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?

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.

What is lightning?

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

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.

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

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

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

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

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

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

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

Why do people hate fat people so much, even people who aren't exactly supermodels themselves? It seems like such a deep, passionate hatred, like they're offended by fat people just existing. Fat people didn't do anything to them, so why hate them?

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?".

This device then solves the entire problem.

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.

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

Edit 2024–10.

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

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

In schematic diagrams this is the symbol for a fuse:

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

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

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

There are three different concepts here that are getting confused.

The other is “what does a “fuse” do?”

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

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

A circuit breaker is similar, but is resettable.

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

(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.

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.

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

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

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

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

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

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

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

He then asserts :

What does a fuse do?

Upvotes:

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.
