What is AC 380?

AC 380 refers to a three-phase alternating current (AC) voltage standard of 380 volts. This voltage level is commonly used in industrial settings to power large machinery and equipment. The three-phase system offers several advantages over single-phase systems, including increased efficiency and the ability to carry more power over longer distances with less energy loss. The three-phase configuration also provides a more consistent and stable power supply, which is crucial for the operation of sensitive machinery that requires precise voltage and current levels.

Technical Specifications and Components

AC 380 systems are designed to handle high power loads, making them ideal for industrial applications. These systems typically consist of three conductors, each carrying an alternating current of the same frequency and voltage amplitude, but with a phase difference of 120 degrees. This configuration allows for a continuous power supply, minimizing the risk of power interruptions. The three-phase power system inherently balances the load, reducing the likelihood of outages or equipment failure due to uneven power distribution.
