Discover the operating principles of a three-phase induction motor
The induction motor is a type of electric motor that operates using two rotating magnetic fields. It is a device widely used in industrial activities, especially those involving power generation. The stator remains fixed to the motor housing and functions to conduct energy and convert it into electricity.
The Impact of Power Outages on Brazilian Businesses
Power supply interruptions are a major concern for businesses across Brazil. A recent survey released by the National Confederation of Industry (CNI) revealed that 67% of companies using electricity in their operations suffered losses due to power outages.
The use of temporary power in data centers
Mobile data traffic continues to surge. Market forecasts indicate that by 2018, traffic will reach 1,182.5 exabytes globally. With this volume, the demand for cloud storage strengthens as an irreversible trend, driving the need for data centers. In Brazil, it’s estimated that 30 data centers are operational, a number significantly lower than the approximately 1,500 in the U.S. market, indicating substantial growth potential.
In which situations is it necessary to have a mini power generation plant
In most parts of the country, having electricity at home or in the workplace is taken for granted. No one really thinks about the journey electricity takes before it reaches the switch or the outlets that power electronic devices and appliances. This energy is supplied by utilities, but in many regions of Brazil.
The high cost of energy in Brazil
Brazil has one of the most expensive energy rates in the world, ranking 6th according to Firjan in 2015. The cost per MWh was R$ 402.26, which is 46% higher than the international average of R$ 275.00. The main culprit is the excessive taxation, accounting for 50% of the final bill, including federal, state, and municipal taxes.
The challenge of providing temporary power for the oil and gas sector
Oil extraction in Brazilian territory can be divided into before and after the discovery of the pre-salt layer. With the exploration of this new source, oil production increased from an average of 40,000 barrels per day in 2010 to 1 million barrels per day in 2016. One of the major challenges is the use of temporary power. Located far from the mainland, these platforms are not connected to the System.
Learn how to calculate ripple voltage and its usefulness
Ripple voltage represents minimal variations in DC voltage signals, crucial for sensitive electrical systems that cannot tolerate fluctuations. In a 12V system, variations from 11.99-12.01V (20 millivolts) can cause damage. Measured as a percentage, it detects variations in the millivolt range. The oscilloscope is the most commonly used equipment for measurement, identifying voltage peaks and effective values to pinpoint variations in electrical circuits.
What is electrical impedance? Learn about its calculation and applications!
Electrical impedance measures a circuit’s ability to resist the flow of electric current, defined as the total resistive load of alternating current circuits. Each material has a different impedance determined by its atoms. Expressed in Ohms, it is calculated by the relationship between voltage and current according to Ohm’s Law, essential for the correct sizing of electrical equipment.
Rainy Season and Power Supply Failures
After the 2015 water crisis, 2016 saw an increase in rainfall. Despite improvements in reservoir levels, some regions, like the Northeast, have accumulated volumes below expectations, and the supply crisis is not averted.
What does a power reactor do?
The reactor, also known as a ballast, is an essential device that limits electrical current in fluorescent lamps and other equipment. It functions as an inductor that adjusts the network voltage to the optimal power of the devices. Its dual role in fluorescent lamps includes generating the impulse to light them and maintaining the current at a safe level, preventing explosions. Available in traditional and high-performance versions for different applications.
