A completed internal wiring and earthing system inside a substation protection or control panel. The setup demonstrates precision and adherence to international electrical standards, with the following key features:

• Earth Busbar (Copper Strip): Mounted at the top with bolted connections to the panel chassis, ensuring solid bonding and low impedance grounding path.

• Color-Coded Control and Signal Cables: Neatly routed using cable ties and wire markers, aiding in clear identification and future maintenance.

• Brass Earth Terminals with Ferrules: Secure termination for each earth wire, providing robust connection and reliable fault current dissipation.

• Galvanized Steel Cable Entry Plate: With sealed grommets to ensure clean cable routing, physical protection, and potential shielding.

• Protective Labeling and Safety Signage: Includes high-voltage and anti-tamper warnings to comply with electrical safety codes.

• Compliant with IEC 61439-1/2 and IEC 60204: Covering electrical panel safety, wiring practices, and earthing standards.

This internal layout was assembled and tested as part of the substation protection and control system, contributing to the operational safety and reliability of the entire power infrastructure.
