TEST LOADING DEVICE Russian patent published in 2016 - IPC G01R31/34 

FIELD: test equipment.

SUBSTANCE: test loading device 1 comprises: a resistive unit 20, which contains one or more of the resistive groups, having a set of resistors, and can be connected to source of power passing tests under load; cooling fan 10 to cool resistors resistive unit 20; 80 unit control. Note here that resistive unit 20 is equipped with device 20a determining current/voltage, which determines the current flowing through resistors, resistor group or resistive unit 20, or voltage applied to resistors, resistor groups or resistive unit 20, and 20b determining temperature, which determines temperature of discharge after resistive unit 20. Cooling fan 10 is equipped with device 10a for state determination of rotation of the cooling fan. Unit 80 control controls switching off, the power supply is disconnected from the tested power source on resistive unit 20 based on information from device current/voltage determination 20a, 20b temperature determination of information and information from 10a determining the state of rotation.

EFFECT: technical result consists in improvement of accuracy of fault detection.
