Construction Supervision

A Turning Over Certificate was signed by the Contractor and Consultant on 19 th August 2004 including works under Variation Order Number 1. There remains several items on the snag list which cannot be completed until Load Dispatch Centre (A3) agrees to a shut down at Lien Chieu substation and a re-energisation of the Hai Van Substation.

Contractor completed and delivered all the As- Built documentation required by contract in July. This included as-built drawings, and Operations and Maintenance manuals.

Permanent energisation (power supply) service will be carried out when a number of issues relating to operations and contract to pay for power consumption is resolved. It is intended to have the Hai Van substation permanently energised as soon as possible. SITOC inspection was carried out before and during test energisation in end of June/early July

Activities for Coming Months

Work to be done at Lien Chieu 110KV Substation

- Replacing faulty REL 551 relay with a new relay

Existing relay is giving IRF (Internal Relay Failure) alarm to the SACO alarm annunciator but does not show any alarm on the relay itself

- Replacing faulty REL 543 relay with a new relay

Existing relay internal supervision is giving error message for one of the analog channels when staring up.

- Modifications for Circuit Breaker Failure Protection circuits (REF 543)

Existing CBF protection circuits for Hoa Khanh and Hai Van circuit breakers are latching and therefore not working properly.

- Testing of the CBF protection functions and tripping the Hoa Khanh and Hai Van circuit breakers.

Complete outstanding items of supply spare parts and tools.
