At the Amazonian Nokia Foundation II Science Fair (FCA), students presented the unprecedented "electronic device suppressor effect," which successfully protects electronic equipment from damaging urban lightning storms. The FCA is part of the 11th annual National Week of Science and Technology (SNCT), which ended November 7th, in eastern Manaus, in the SESI Worker Club. The National Week of Science and Technology is coordinated by the State Office of Science, Technology and Innovation (Secti-AM).
According to the student Yasmin Torres, the electronic suppressor automates electronic systems for homes or businesses to protect appliances against electrical discharges from lightning. "These lightning storms occur in periods when it rains heavily. Here, in the Amazon, that is during the months from November to March," he said.
The device works while plugged into an outlet and the appliance, and creates a source of protection in case of a lightning strike." According to information from the National Institute of Meteorology (INMET), the greater the amount of rain, the more likely that there will be lightning," said another student participant of the project, Daniela Caroliny.
The equipment operates with a programmed sensor to detect rain storms, and if it receives a large volume of water, the power supply is cut to the machine." So the user will not be burned, nor will the device cause damage to your operation. Despite having a similar function as a lightning rod, it is much cheaper and does not require skilled labor to be installed," said Caroliny.
According to the National Institute for Space Research (INPE), Brazil is among the countries with the highest incidence of lightning in the world, with about 70 million rays that strike the country every year, which equates to an average of two or three lightning strikes per second.
