HV auxiliary power voltage transformers (SSVT) in paper-oil and SF6 insulation from 72.5 kV to 550 kV


An SSVT – station service voltage transformer can be a very useful device at an HV substation. SSVTs can be used as supply control and/or auxiliary needs in a power substation, replacing standard power transformers, but also as a supply source in remote substations, mining, and emergencies.


PVTs can be considered “install-and-forget” devices that have proven their ability to operate reliably under all conditions. Because of their advantages, substation design can also be simplified and construction costs can be reduced.


PVTs offer great potential for wider use as primary power and distribution units in remote areas near overhead power lines.
