Summary
The diagnostic unit is used for software-programmable tests of various power DC units.
Description
The unit makes it possible to carry out overall tests of
electrical machines in automatic controlled mode. In addition, machine
parameters are measured at each operation mode of the unit. All these measured
values vs. their corresponding extreme values give objective information,
analyzing which it is possible to estimate the technical state of the test
machine.
