Situation

Melbourne Tunnel Metro Project contacted Greenwood Solutions to conducts a series of comprehensive primary injections tests on all their pumping station switchboards. The role of these  giant slurry pumps is to maintain a dry safe working environment whilst tunneling.

Action

A team of Greenwood Solutions technical personnel put together a action plan and armed with the latest primary injection equipment proceeded to test over thirty three Circuit Breakers and, in addition, multiple RCDs. The results were analysed and presented as a comprehensive report.

Outcome

The detailed report’s job is to identify, if any, potential issues and was presented to the electrical contractor in charge. Any decisions regarding rectifications was then up to the contractors.
