Using a dynamic simulation software which directly controls multiple conventional test sets for simultaneous injection of test currents into all bay units is very efficient, since it does not require any rewiring all the time. Resources For Electrical & Electronic Engineers. When 52-2 CT fully saturates, its magnetic field impedance is effectively 0.00. Generally, the HiPot test is run at an exaggerated voltage level of 2X the operating voltage plus 1,000 volts to ensure safety and performance even in extreme scenarios. 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. This checklist has been built to make it easier for inspectors to check transformers/motors, direct current (DC) battery system, and the operation and testing tools and equipment and perform efficient lightning protection system, busbar trunking system, circuitry checks, and more.
