WHAT WE HAVE DONE
Switchboards consist of copper plate/bar which is used in ship’s main and emergency switchboards to conduct electricity from generators or from one electrical terminal to another. There are no electrical wire connections inside main and emergency switchboards for power switching of generators.
All high voltage and high current systems are connected by bus bars.
WHAT TO DO
Switchboards copper bars are connected together with the help of nut bolts, which transmit electricity as required. During normal ship operations, the busbar connections are subjected to ship’s harsh environment along with the vibrations generated by the ship and ship machinery such as main engine, auxiliary engines , compressors etc. These vibrations cause loosening of nut bolts in the busbar, which can lead to short circuit or any other type of accident. Loose connections inside the switchboard can also lead to sparks that can cause fire.
During maintenance , cleaning of all busbars also is necessary. This can be done by vacuum cleaner and with special dielectric cleaners.
