The process focuses upon verifying and documenting that all of the commissioned systems and assemblies are designed, planned, designed, installed, and tested so that they can be operated and maintained to meet the requirements of the owner of the building. Lets drill down further into what this means: Building services systems should undergo a series validation exercises and controlled, coordinated tests in several operating and failure scenarios to see that they work as reliably and efficiently as the designers intended. That means that the current will want to flow around the outside of the equivalent circuit because the outside circuit has a lower impedance path during external faults. This is all the concept of busbar protection. Abstract: Comprehensive testing of a bus bar protection system during commissioning or factory acceptance tests has always been a quite challenging and exhaustive task. Reading will vary widely between site due to length of run, humidity etc. The test runs a specific electrical voltage (AC or DC) through the conductor while a ground is created on the adjacent conductors to verify that there is no electrical path between them.
