Understanding Electrical Voltages: Low, Medium, and High

In the field of electrical engineering, understanding the different voltage levels is crucial for ensuring safety and efficiency in various applications. Here’s a quick guide to low, medium, and high voltages and their typical applications:

?? Low Voltage (LV): Typically up to 1,000 volts AC or 1,500 volts DC. Common applications include:

• Residential wiring: Powers household appliances, lighting, and outlets.
• Commercial buildings: Lighting systems, HVAC, and office equipment.
• Small industrial machinery: Operates tools and small machinery.

?? Medium Voltage (MV): Ranges from 1,000 to 35,000 volts. Used in:

• Distribution networks: Transmits electricity from substations to local transformers.
• Large industrial facilities: Powers heavy machinery and equipment.
• Mining operations: Supplies energy to mining equipment and infrastructure.

?? High Voltage (HV): Above 35,000 volts. Found in:

• Transmission lines: Carries electricity over long distances from power plants to substations.
• Electric railways: Powers trains and transit systems.
• Large-scale industrial plants: Supports major manufacturing and processing operations.

Understanding these voltage categories helps in selecting the right switchboards and electrical solutions for your projects, ensuring both safety and performance.
