The condition of the insulation of rotating machines is evaluated by performing high voltage tests typically during manufacturing, commissioning, maintenance, or repairs. These tests are typically referred to as static tests because they are performed while the machine is offline.High voltage DC tests are used to evaluate the status of the ground wall insulation system with tests such as insulation resistance, polarization index, dielectric absorption ratio, step voltage, and dielectric voltage withstand tests (hipot).
