What is the oxide oxide oxide?

Varistor of metal oxide oxide (MOV) is a device used as part of an electrical device. The word varistor is short for variable resistor. A resistor is a circuit that does not perform well. This is useful to check how much electric current travels to certain parts of electronic devices. The metal oxide varistor will be very well performed by low electric current, but ceases to perform when the current reaches high voltage levels.

Thanks to this property of the varistor of metal oxide oxide, it is ideal for use in electric surge protectors. At normal current levels, it simply transmits electricity to the device connected to the surge protector. However, in the event of a power surge, the MOV turns the current to itself and prevents it from reaching connected devices. This will protect sensitive electronic components, such as computer chips that can be damaged by excessively large voltages. In the event of a sudden increase in power can MOV responnd much faster than afterDiscussion components of overvoltage. These substances give the varistor the quality of the current passage at a normal household. When the electric current rises to a certain point, called the release point or the voltage of the release, the small particles of the zinc oxide begin to perform only the current between themselves. This prevents the high -level current in the transition to the rest of the surge protector or the device into it.

Varistor of metal oxide is not a perfect surge solution. They are cheap for production, which means that they are often used in cheap surge protectors. The disadvantage is that if the power surge stops, they can burn effectively, but the user may not have any idea that this has happened. When the energy overvoltage occurs, the connected device will not be protected. Better but more expensive, surge protectors will have indicator light that shows the state of the IOC.

There is also a risk of fire when metal oxide varistor absorbs high voltage and burns. FromThis is required by the US Consumer Product Security Commission and similar agencies in other surgery guarantees. This is also the reason why computers are not just about their computers. The best solution is to have an overvoltage protector containing multiple components and fuses in the MOV series. If the varistor fails, other components still protect connected devices from damage.
