Power Transformers: Types and How to Choose for My Business

Electrical transformers convert current and voltage values through windings and a core. Main types: residential autotransformers (110V/220V), electronic (low voltages), distribution (street poles), power (industrial substations), and low voltage (internal circuits). Choice depends on purpose, location, and specific business needs. Incorrect voltage use can permanently damage equipment.
Understand the Differences Between Volts, kVA, and Watts

Volts measure electrical voltage (potential difference between points), kVA indicates apparent power in generators (1000 volt-amperes), and watts determine the actual consumption of electrical equipment. For generator sizing, it’s essential to understand these three measurements: voltage for operation, apparent power for capacity, and watts for effective consumption. Knowing the differences helps in choosing the right equipment.
Five Scenarios Where Temporary Power is Crucial for Mining
Mining accounts for 4% of Brazil’s GDP and 25% of the trade balance, with iron ore exports growing 25.4% in 2018 (394.24 million tons). China, the Netherlands, and Japan are the largest importers. In remote locations without access to the SIN, temporary power is essential in five scenarios: climate control at depths for worker safety; operation of large machinery from exploration; transport of heavy materials from depths; security and ventilation systems; and supply throughout the mine’s lifespan. Tecnogera offers customized solutions considering climate, terrain, and specific demands.
Rain and High Temperatures Drive Temporary Energy Market

The International Research Institute for Climate predicts a 70% chance of El Niño in 2019, leading to dry weather in the Central-North and wet conditions in the South/Southeast with high temperatures and heavy rains. Storms cause power outages disrupting business operations. In retail, demand for temporary energy is expected to grow by 50% at the end of 2018 and the beginning of 2019. Rental becomes a viable alternative including generators, accessories, and 24-hour service, avoiding high acquisition costs.
Tecnogera secures contract with Petrobras
Tecnogera has won a bid to supply temporary power to Petrobras for three years (extendable for an additional two), covering facilities in 15 states. The contract includes power generators, cables, transfer switches, and accessories to meet demands such as technical failures, shutdowns…
Infrastructure investments will resume growth in 2019
Power generators have been essential to Brazilian infrastructure since the 1970s, supporting sectors like construction, mining, oil & gas, retail, sanitation, telecommunications, and renewables. After a decline in 2018 (1.65% of GDP), investments are expected to rise to 1.85% of GDP in 2019 and 2.03% by 2030. BNDES forecasts a 13% growth in infrastructure over the next three years. Industries such as mining and oil & gas require power generators around the clock. Tecnogera operates over 800 power generator units across 5 states.
Energy demands of data centers
Digital transformation boosts demand for data centers in Brazil, with the market growing 15% annually to reach US$ 1.3 billion by 2020. Data centers operate 24/7, requiring uninterrupted power for processing, cooling, and critical operations. An hour of outage can result in losses of US$ 84-108 thousand per company. Solutions include 45-2,250 kVA power generators on standby with automatic transition, as well as temporary use for maintenance and capacity increase.
Advantages of StandBy Rental
The e-book on the advantages of StandBy rental analyzes important variables for companies, including cash flow impact, cost of capital, and asset value (new generators depreciate by 20% in the first year). It also covers…
Tecnogera provided an energy security solution for Pacaembu Stadium

Tecnogera ensured energy security at Pacaembu Stadium during the Santos vs. Nacional match for the Copa Libertadores, serving over 20,000 fans. The solution was implemented following a power outage in a previous match that halted the competition for 49 minutes. The company supplied 2,300 kVA through three generators operating in permanent parallel, far exceeding the required 550 kVA. The project, developed in partnership with the Municipal Sports Department, ensured uninterrupted power supply throughout the entire match.
How a Temporary Power Plant Works in Mining
Mining is an essential activity for the global economy, providing the necessary mineral resources for various sectors, from construction to electronics manufacturing. However, mineral extraction often takes place in remote locations, far from conventional power grids. This is where temporary power plants come in, offering customized solutions that ensure a continuous power supply for mining operations.
