LOAD TESTING MACHINE Russian patent published in 2015 - IPC G01R31/34 

FIELD: electricity.

SUBSTANCE: machine comprises six resistor units, six cooling fans, insulators between resistor units and cooling fans and connecting cables. Each resistor unit comprises several steps of banks of resistors arranged along Z axis. Each group is formed by several rod resistors parallel to X axis connected in series and arranged with pre-set intervals along Y axis. Six cooling fans are facing towards resistor units along Z direction. Connecting cables are cables that are used for series demountable connection of neighbouring banks of resistors along Y axis of two neighbouring resistor units along Y axis with an interval between them no less than the second distance. Each insulator has a size corresponding to the rated voltage of the target power supply during load test of the power supply which is performed using the group of resistor units. The group of resistor units has series connected resistances of two neighbouring resistor units along Y axis with the interval between them no less than the second distance.

EFFECT: performing load test by simple adjustment.
