Semiconductors: What They Are, Types, and Applications

Semiconductor materials have an intermediate level of electrical conductivity between conductors and insulators. Silicon and germanium are the most common, with silicon being more widely used due to its more effective chemical bonding. Gallium arsenide…

What is an Enclosed Generator? Protection and Low Noise

An enclosed generator is a power generation equipment featuring a metal structure internally lined with thermoacoustic foam, significantly reducing operational noise. Its features include weather protection, noise levels between 75-85 decibels, and easy maintenance through side doors. It’s ideal for hospitals, schools, libraries, hotels, and environments requiring low noise levels. Tecnogera offers modern and economical enclosed generator sets with comprehensive service.

How does a manual power generator work?

The manual power generator is equipment that ensures convenience and safety in various environments with simple operation, ready to be activated at any time during power outages. Its operation is straightforward, activated by a crank or device that creates tension between internal motors, converting mechanical energy into electrical energy. It requires preventive and corrective maintenance by specialized companies.

What are the sources of electrical energy?

In Brazil, 95% of electrical energy is generated in hydroelectric plants using the force of water to convert potential energy into kinetic energy by spinning turbines. Other sources include solar with panels capturing radiation, wind with blades driven by wind, biomass through the decomposition of organic matter, nuclear with uranium nucleus splitting, fossil using oil and coal, geothermal obtained from magma, and tidal by building dams in the sea.

How can an electric meter help with savings?

The electric meter, commonly known as the power meter, measures and controls energy consumption in homes, businesses, and industries. It features a metal disc that spins according to the amount of energy used, displaying data in kWh. It can be an excellent ally for saving energy by providing real-time consumption information, allowing you to identify excessive usage and detect electrical current leaks that increase the electricity bill and can damage equipment.

What is the ANEEL (National Electric Energy Agency) auction?

ANEEL auctions are mechanisms through which distribution concessionaires, permit holders, and authorized entities ensure market supply. In the Regulated Contracting Environment, selling agents and distributors establish contracts through bidding processes. These are bidding processes to contract the energy needed to meet future demand, setting prices and energy sources that directly impact consumer tariffs, and are essential for the balance of the electric sector and the prevention of rationing.

Caring for a Gas Power Generator

The gas generator is a safe piece of equipment installed in various residential, commercial, and industrial environments for energy supply. Its main advantage is the quick response to blackouts, as it activates swiftly to normalize the power supply. It operates by directly connecting a gas line to the generator, allowing…

What is the purpose of an electrical cable protector?

Safety is paramount in electrical installations to prevent serious accidents and equipment damage. Electrical cable protectors ensure that power is distributed correctly without causing issues. They shield against external factors like cigarette sparks or matches that could ignite fires. Solutions include ablative coating, metallic corrosion protection, and junction boxes that organize installations and simplify maintenance.

How does energy import from Argentina work?

Despite its large internal power generation capacity, Brazil will start purchasing energy from Argentina and Uruguay. According to the Ministry of Mines and Energy (MME), Petrobras and Eletrobras are authorized to import between 570 and 2100 megawatts until the end of 2015. This process is based on requests from the ONS and differs from commercial negotiation as Brazil will not buy energy but will generate electricity credits for neighboring countries. This exceptional and temporary measure includes contracting transmission systems and using interconnection facilities between countries.

Check the status and levels of the hydroelectric reservoirs

The water crisis continues to concern Brazilians. Beyond the possibility of water shortages, there’s growing worry about energy supply failures. Much of the energy comes from hydroelectric plants that use water power. Reports from ONS indicate that reservoirs in the Southeast and Midwest should reach 37%, eliminating the possibility of rationing. The country has increased the use of thermoelectric plants, reaching 20% of consumption, raising electricity bills. A combination of reduced consumption and economic slowdown has averted the need for rationing, despite 17 of the 28 main reservoirs having lower volumes than the same period last year.
