ERECTION SEQUENCE AND PLAN FOR GENERATOR PART-II ABC OF THERMAL POWER PLANT.

Some of the checks are to be carried out before rotor threading is  given below

All electrical tests (dc resistance, IR value and impedance) are carried out on rotor.

Stator is thoroughly cleaned and free from foreign elements like dust, oil/water, spanners, screwdrivers etc.

All electrical tests (dc resistance, IR value) are carried out on stator.

Check healthiness of thermocouple/RTDs of stator core /winding.

Check locking of bolts of clamping plate of stator overhang. Check busbar supports for tightness .

Tightness of compressor blades for axial movement is checked

Check and ensure for locking of all balancing weights to be checked visually / hand feel.

Measure and record male spigot/journal dimensions of rotor on both ends.

Vacuum cleaning of all ventilating holes is carried out and transportation packing & blower protection cover on rotor is removed.

Check through-ness of radial ventilating holes of rotor winding 

Stator is getting  ready for rotor insertion.  please notice the arrangement of maxpuller both sides  and the

piece of rubber solid  laid inside the stator.

Zigs and fixtures are moved and are getting placed in position.

Rotor is brought near to stator for insertion. Please look out for zigs and fixtures
