Testing also confirms consistency in the outputs of critical manufacturing processes, confirming that there are no defects that affect the parts performance or expected lifespan. This test is especially important for medium voltage, multilayer laminated bus bars, inverters, and any critical power conductor applications where electrical insulation is of paramount importance. The commissioning procedure of substation busbars for differential protection and other busbar protection schemes involves a large number of input and output circuits that require a verification check in both the primary and secondary circuits. For example, a HiPot test verifies that the multiple conductive layers within a laminated bus bar are sufficiently insulated from one another at a specified voltage. REB611 is a dedicated busbar protection relay designed for phase-segregated short-circuit protection, control, and supervision of single busbars.
