Testing of electrical machines

Aims of thermal tests are:

→ determination of the temperature characteristic active parts of generator (stator and rotor windings, stator core );

→ assessment stability of the temperature characteristic active parts of generator over a operating period;

All types of testing meet the requirements of international standards.

→ correction P-Q capability diagram indicating the limits of operation;

→ capability check of generator at the increase total power (remarking).


Aims of electrical tests are:

→ determination of no-load saturation characteristic;

→ determination of three-phase sustained short-circuit characteristic;


Aims of ventilating tests for hydrogenerator are:

→ assessment of job air coolers;

→ flow measurement cooling air.
