Appendix D – CT Phase Shifts
Most current transformers sold by Siemens have phase shifts from a few tenths of a degree up to a few
degrees. For energy meters, this phase shift can produce accuracy errors. However, DENT’s ViewPoint
HD software can compensate for CT phase shifts to help maximize reading accuracy. Siemens CTs are
listed below with their corresponding phase shift values If you are using the desktop version of ViewPoint
HD, these values will automatically be populated for you when using the CT Picker. If you are configuring
your meter through the MD-HD Web App, use the table below to find the correct phase shift value.
