Low Voltage (LT) panels are essential components of electrical distribution systems, regulating and controlling the flow of electrical power. They are crucial for ensuring the safety and efficiency of electrical installations in various settings, including residential, commercial, and industrial facilities.
Key Components of an LT Panel
- Incoming and Outgoing Feeders: These are the primary connections for power input and output.
- Circuit Breakers: These devices protect circuits from overload and short circuits.
- Metering Units: These measure the consumption of electrical energy.
- Busbars: These conduct electrical current within the panel.
- Control and Protection Relays: These devices monitor and control the operation of the panel.
