Dismantling cleaning of 3Phase syn Generator of Unit II Make VA Tech Hydro 750 RPM rated output 6MW cleaning of Stator Rotor and checking conduct necessary tests of stator rotor complete in all along with testing of generator under Khauli PH Darini

Amount

Dismantling:-Dismantling/Overhauling of synchronous generator, DE And NDE Bearings, stator & rotor complete in all respect. Cleaning & Testing:-Cleaning of stator and rotor with air, deep cleaning of stator winding and rotor poles with dry ice, varnishing of stator and rotor, complete heating and drying of stator and rotor with the help of blower, heater etc. , apply epoxy gel coat on windings ,poles of rotor etc., checking of safeties like RTD and BTD for proper functioning. Following basic tests will be conducted for rotor & stator:- Rotor * Insulation Resistance Test(Before & After) * Pole drop voltage test * Inductance & AC impedence test. * Other basic tests will be performed. Stator * Dielectric absorption resistance test. * Insulation Resistance test. * Polarization Index test. * Slot vegas & DC winding resistance measurement. * Other basic tests will be performed. Assembling & Alignment:-Assembling of complete synchronous generator including stator & rotor and alignment of DE & NDE bearings with turbine as per satisfaction of Engineer-in-charge under Khauli Power House Division HPSEBL, Darini.
