The project<\/strong><\/p>\n

Electrical retrofit was carried out on an existing relay system where old and unreliable relays needed to be replaced with new programmed, tested and documented relays.<\/p>\n

Cetec Energy programmed and tested new relays off-site, prepared comprehensive project documentation, and oversaw the dismantling, installation and commissioning.<\/p>\n

Planning and scheduling<\/strong><\/p>\n

Assessment of the overall impact of the relay replacement and identified risks associated with integration, wiring and configuration in the existing power system.<\/p>\n

Implementation<\/strong><\/p>\n

Carrying out the refurbishment from dismantling to commissioning ensured functional equivalence and verified logic and settings against the original schematics.<\/p>\n

Review<\/strong><\/p>\n

A third-party review confirmed that the protection features were maintained or improved - the system met reliability and performance standards.<\/p>","protected":false},"excerpt":{"rendered":"
