Thermal imager monitoring of generators

Thermal imager monitoring allows the distribution of thermal field and heating of running turbogenerator construction parts to be evaluated.

Renovation of hydrogenerators

Elaboration of Hydrogenerator Renovation Project with renewal and extension of hydrogenerator normal life time, increase of rated output and expansion of permissible operating conditions range.
Submission of  design and repair documentation, elaboration of tender documents for new generators order and old generator reconstruction.
Renovation of hydrogenerator separate assembly units and systems:

• stator cores and windings;
• poles and interpole connections;
• air- and oil- coolers
• thrust bearings and guide bearings;
• oil reservoir seals;
• ventilation and cooling systems;
• braking systems;
• slip rings and brushgear;
• excitation systems;
• thrust bearings and bearings with application of elastic metal-base laminate coating.
