We catalog as Professional LED Lighting those products especially aimed at installers and professionals who are dedicated to carrying out large-scale projects.
Understanding what electrical voltage is is essential in a wide range of contexts, from everyday life to specialized fields such as electrical engineering and electronics.
In domestic situations, knowledge of electrical voltage allows you to understand how energy works in your homes and make informed decisions about the use of electrical devices and home safety.
In professional environments, such as engineering and electronics, understanding electrical voltage is essential for the design, maintenance and repair of electrical and electronic systems, ensuring safe and efficient operation of equipment and circuits, as well as the prevention of potential health and safety risks.
1 What is electrical tension?
Electrical voltage is a fundamental concept in the field of electricity that is usually familiar to most, although not necessarily fully understood. Beyond simply being a technical term, it is the driving force behind the flow of current in any electrical circuit.
Also known as electrical potential difference, it is the force that drives the flow of electric current through an electrical circuit. It is measured in volts (V) and represents the amount of potential electrical energy available to do work per unit of electrical charge.
In essence, it is the "push" that drives electrons to move along the wiring, allowing complex electrical devices and systems to function.
2 Types of electrical voltage
There are several types of electrical voltage, classified mainly according to their voltage level and their specific application in electrical systems. Let's see the most common ones and their main uses!
Low electrical voltage
Low electrical voltage refers to voltages that generally range from 0 to 1000 volts in electrical distribution systems. It is commonly used in residential, commercial, and industrial applications to power low-power devices and equipment, such as appliances, lighting, and electronic systems.
Electrical medium voltage
Medium electrical voltage covers voltages ranging between 1000 and 35,000 volts in electrical distribution systems. It is used in industrial and commercial applications to power motors, transformers, high-power lighting systems and other medium-power electrical equipment.
High electrical voltage
High electrical voltage refers to voltages that exceed 35,000 volts in electrical distribution systems. It is mainly used in long-distance electrical power transmission applications, such as power transmission lines, electrical substations and high-power equipment.
Remember that each type of electrical voltage has its own characteristics, safety requirements and specific applications in the design and operation of electrical systems. At GreenIce, we believe that it is very important to understand and properly manage the electrical voltage corresponding to each situation to ensure safe and efficient operation of the electrical system.
