How to calculate residential electrical energy demand?

A Tecnogera employee smiles wearing a hard hat and white shirt in front of orange machinery outdoors, with hills in the background.

The electrical system composed of networks and substations forms a distribution grid for a large number of users. Demand (expressed in kW) is the maximum usage limit requested, obtained by summing the installed loads in operation. Applied individually to consumer units with voltage ≥2.3kV (Group A). It constitutes a commitment in the supply contract. Consumption measured in kWh indicates the feeding period. When the measured demand exceeds the contracted amount in the billing cycle, the consumer is subject to an extra charge. Proper planning ensures service to all users.

Understand What Electrical Resistance Is

Electrical resistance is the ability of a body to oppose the flow of electric current. When current flows through a conductor, it creates a high number of free electrons that collide with each other and with the metal’s atoms, hindering movement. Influencing factors include the conductor’s resistivity, length, cross-sectional area, production material, and operating temperature. The calculation uses Ohm’s Second Law, considering resistivity, length, and area. The Joule effect converts electrical energy into thermal energy when electrons cannot overcome the resistance, applied in showers, dryers, and other appliances.

What are electrical conductors and insulators?

All matter is composed of atoms, which consist of small particles known as neutrons (which have no charge), protons (positively charged particles), and electrons (negatively charged particles). These particles are responsible for carrying electric current through materials.

UPS System: Understanding Uninterruptible Power Supply

An open electrical panel that's part of a UPS system. With a tablet and a digital pen in hand, he analyzes the information while observing the wires and components of the panel against a gray wall.

The UPS system provides stabilized power instantly when there’s a disruption in the primary grid, differing from other emergency systems. UPS units prevent abrupt shutdowns of computers and electronics, ensuring 10-15 minutes of operation through a battery charged by the electrical grid. There are online types with double conversion AC-DC-AC and offline with…

What is an electrical current transformer and where is it used?

The image shows large electrical insulators and cylindrical metal components, including a large transformer, at a power substation under a blue sky.

Electrical installations often require an increase or decrease in the voltage supplied by energy companies. In these cases, a transformer is needed, a device that converts electrical voltage according to the needs of the equipment, ensuring its proper operation and safety.

Understand the electrical wire color code chart

The image emphasizes the importance of care and attention during work. Remember: knowing the color code for electrical cables is crucial for ensuring safety.

The colors of electrical wires help identify their functions: light blue for neutral, green or green-yellow for ground, and red, black, or brown for live. Following this pattern ensures more safety in installations and maintenance.

Learn how to properly store liquids and other flammable products

Companies involved in processing, supplying, or transporting flammable products must strictly adhere to the guidelines of Regulatory Standard NR-20. Combustible liquids (with a flash point between 70°C and 93.3°C) should be stored in steel or concrete tanks, properly protected against vibrations, physical damage, and heat sources. Facilities must include natural ventilation systems, fire protection, appropriate signage, and follow detailed technical specifications to ensure the safe storage of these hazardous materials.

Electric current: concept, types, and applications in generators

The wooden utility pole with insulators supports three wires, illustrating energy solutions, under a partly cloudy sky.

Every electronic device requires a power source to operate, whether from a battery or an outlet. Electric current is the orderly movement of charge-carrying particles (electrons) that occurs in a conductor when there is a potential difference between its ends, known as voltage. Its intensity is measured in Amperes (A) and can be calculated using the formula I = ΔQ/Δt. There are two main types: direct current (batteries) and alternating current (power grid).

The importance of containment basins for generator sets

A large industrial diesel power generator in white with a black base, by Tecnogera. The equipment features a rectangular shape, modern clean lines, and a control panel with gauges on the front left side. It also includes various ventilation levels and safety labels. The photo was taken against a simple white background.

The containment basin is a safety item that prevents fuel leaks from contaminating the soil and water resources in the area where the equipment is installed, and is also an item checked during environmental inspections and audits by corporate clients.
