See how power generator sizing is done

Proper generator sizing is crucial to ensure adequate operation during electrical system failures. The process considers electrical load, installation environment, temperature, pollution, and altitude. The power factor is calculated by considering the difference between apparent power (Volt-Ampere) and active power (Watt), as well as alternator efficiency losses and the engine’s mechanical power. The sizing must adhere to an 8-hour operation and 4-hour rest regime.

What are the differences between electric motors and generators?

Electric motors and generators operate similarly through electromagnetic induction, but they serve opposite functions. The generator converts mechanical energy into electricity by applying force to spin the rotor and create a magnetic field. The electric motor does the reverse process, transforming electrical energy into mechanical energy through fields…

How does energy exchange work?

Energy exchange enables the transfer of electricity between countries or regions in cases of supply shortage or surplus. In Brazil, the National Interconnected System (SIN) facilitates these exchanges through four regional submarkets. The country primarily engages in exchanges with Argentina, Uruguay, Paraguay, and Chile, enhancing the utilization of energy matrices and reducing costs.

How the Electric Energy Tariff Flags Work

The tariff flag system created in 2015 by ANEEL signals to consumers the cost of power generation through three colors. Green: no additional charge, favorable conditions for hydroelectric plants. Yellow: R$ 1.50/100kWh, limited use of thermoelectric plants. Red 1 (pink): R$ 4/100kWh and Red 2: R$ 6/100kWh, higher reliance on expensive thermoelectric plants. Generators can assist companies during peak hours to reduce costs during unfavorable flags, with monthly planning based on ANEEL’s information.

What is a manual power generator?

The manual power generator is operated by a crank instead of automatic start, converting mechanical energy into electrical energy through internal engines. Ideal for hospitals, schools, and supermarkets that rely entirely on electrical power. Key advantages include mobility (small size, some with…

How does a power generator work?

A power generator is an essential piece of equipment that meets energy needs during power grid failures, serving as a primary or backup source. It offers advantages in security (ensuring operational continuity and alarm systems), agility (quick automatic response), and versatility (applicable in hospitals, industries, airports, events). To choose the right one, consider emergency or continuous use, available physical space, access to the power grid, and fuel type (diesel or gasoline). Tecnogera offers customized TurnKey solutions.

Is renting a generator more cost-effective than buying one?

Renting a generator involves a significantly lower investment compared to purchasing, with multiple advantages: preventive and corrective maintenance included, equipment always inspected and in perfect condition, 24/7 specialized support from experienced technicians, and full tax deduction. It’s a versatile solution for businesses that require uninterrupted power like…

Do you know what power generators are?

An electric generator converts mechanical, chemical, solar, or other forms of energy into electrical energy. Composed of two poles (positive and negative), it maintains a potential difference, supplying energy to electrical loads. The simplest type is the dynamo, which converts mechanical energy using a magnet on a rotating shaft to create a magnetic field that generates electric current. Power generator sets, on the other hand, are large-scale equipment consisting of an engine, generator, and fuel tank, recommended for places that cannot afford power outages like hospitals, laboratories, and supermarkets.

What are the differences between an ideal and a real power generator?

A power generator doesn’t create energy but converts other forms (mechanical or chemical) into electrical energy, increasing the potential energy of the loads in the circuit. An ideal generator would have 100% energy efficiency, but in practice, due to electrical resistance, there are always losses. In an ideal generator, the voltage remains constant, while in a real one, it varies with the electrical current.

100 kVA Power Generator – Where to Use It?

The 100 kVA generator offers immediate response during blackouts, making it widely used in construction and various sectors. Its applications include security cameras, alarms, electric gates, common area lighting, events, and industries that cannot afford productivity interruptions. It is also ideal for colleges, universities, and hospitals, ensuring continuous power supply.
