Special tests are conducted only upon explicit agreement between the manufacturer and the end-user. They usually address unique environmental or operating concerns: Chopped lightning impulse tests. Multiple chopped impulse tests. Seismic qualification tests. Fire hazard and internal arc tests. Transitioning from IEC 60044 to IEC 61869-1
This standard functions as a "master document." It establishes common definitions, environmental limits, structural demands, and testing procedures that apply to all instrument transformers, whether they are traditional inductive types or modern electronic variants. The Evolution from IEC 60044
