TRANSFORMER WINDING RESISTANCE METER

TRANSFORMER WINDING RESISTANCE METER

APPLICATION:
This Test set is suitable to measure winding resistance of transformers, single or 3-phase, star or
delta connected up to several MVA. The display indicates the reading of the resistance of each
winding connected to the corresponding channel. The winding resistance value will be displayed
along with units i.e. μΩ, mΩ, Ω. A Temperature sensor is provided in the set to display the ambient
temperature. DC Power source allows the selected current to flow through the winding / windings and
the voltage developed across the winding are sent to microcontroller based measurement circuit,
thereby displaying directly the ohmic value.
