Transformer dc resistance test instrument is an indispensable test project of Transformer after handing in pick up overhaul and change sub-pick up switch. In general using traditional methods (bridge method and pressure drop method) measurement transformer winding group and dc resistance of large power inductance equipment is a time-consuming and time-consuming work. In order to change this situation shorten measurement time and reduce the work burden of test personnel huatian electric power company developed Transformer dc resistance test instrument (hereinafter referred to as direct resistance instrument). It adopts new power supply technology featuring stable performance rapid measurement small volume easy to use high measurement precision and good data repeatability. Measurement transformer around the group and large power inductor dc resistance ideal equipment.
