Hello Peter, The objective of these tests is to ensure that there will be no shorting which would create an electrical shock hazard. This is not an operational test.. the product isn't expected to operate after this test.. The post dielectric test is used to verify if any shorting conditions have occurred as a result of the OVT that would create a shock hazard. To answer your question, Yes, your scenario below would be an acceptable result.
