Online Substation Surveys

Complete Diagnostic Solutions – That’s the Doble Difference

A partial discharge survey from Doble is a non-invasive measurement technique that allows problems to be detected while the equipment remains in service. Using the advanced Doble PDS100 with HFCT/TEV probe, substations can be surveyed in a short amount of time (typically less than one day). Highlighted areas can then be investigated in greater detail using more focused on-line techniques, and problematic areas can be targeted for off-line testing.
