In solar power systems, Low Tension (LT) and High Tension (HT) electrical installations manage different voltage levels. LT systems, typically below 1 kV, are used in smaller setups like residential and commercial solar installations. They involve components like inverters and AC distribution boxes for local power use. In contrast, HT systems, above 1 kV, are found in large solar farms, using transformers to step up voltage for long-distance transmission. While LT is cost-effective and simple for local distribution, HT is essential for efficiently transmitting power to the grid over longer distances. Electrical installations refer to different voltage levels and associated components used for transmitting and distributing electricity.
Low Tension (LT) Electrical Installations in Solar Systems
Voltage Range: LT installations typically handle voltages below 1 kV, usually 400V for three-phase or 230V for single-phase systems.
High Tension (HT) Electrical Installations in Solar Systems
Voltage Range: HT installations typically deal with voltages above 1 kV, such as 11kV, 33kV, or higher.
