? A long-term partial discharge problem within the busbar chamber of switch 52 could have been detected if partial discharge testing was done as part of its regular inspection procedure and was recommended to be included to Belco?s inspection and maintenance protocol.

? An audit and condition assessment of the Belco protection system should be carried out to ensure that it is fully functional. In particular given the changes that have occurred on the network during the restoration process.

? A strategic review of Belco should be undertaken to establish its ideal configuration, ensure optimum protection systems are identified and installed as well as establishing optimum operating and maintenance regimes.

? The objectives being to ensure that uncontrolled outages caused by equipment failures result in minimum disruption with the rapid disconnection of the faulted equipment, leaving the remainder of the network stable.
