Part 1 Open-case inspection
1. Check the packaging without damage, if the damaged boxes be found, it must be reported to the
company.
2. Check parts look no obvious bump against injury appearance, deformation, rust, according to the
actual situation reflected (recommended photos form).
3. Reflects the number of parts according to the number in the packing list.
4After open the important assembly parts case, must keep the parts inside storehouse. Requirements
of storage according to packaging.

a. Positive connects: wrap the aluminum foil outside the hand insulation of the end of the stator
winding. The DC high voltage is connected with the tested stator windings. Rated voltage is set for
the step-up generator. And an insulation bar of 100 M is pu t on the aluminum foil. Then the

Oil feed hole should sealed 100%.Use feeler gauge to check the gap between bearing
and bearing seat , make sure that the contact surface around oil groove is required which
means feeler gauge can only put in 0,02mm in depth max. Use 0.01mm feeler gauge to
check the gap between bearing and bearing seat, the depth is 50-60mm, max 100mm.

Power Plant
Thank you for using our generator equipment,
We would be delighted to serve you.Recently one of our customers didnt take strict control of cleanliness duringinstallation, which leads to great damage to the generator. During accidentinspection we found metal remains inside terminal box. In view of this situation, weremind all customers which are under installing and running take great attention tothis issuer
1. Installation process, half year and one year Maintenance must be strictlyaccording to rules, and supervision to strengthen self-control.2. make sure there are no metal remains or other debris in the stator and terminal3. Cleanliness inspection should take under strict regualtations.All parties should
take part in the inspection and signature for recognition .

Note1Install oil system pipes correctly. Make sure that the pipes connected hydrogen
side turn oil tank is downward-sloping Check to make sure2Oil flushing is
according to regulation. The quality of Seal Oil must be do the rigorous testing
before it run into the bearings3pay more attention to the temperature of seal oil the
temperature arrange from 27to 494Before seal oil system put into use, open
the bracket of hydrogen oil tank for inspection. Check the Hydrogen return oil tank
cleanliness and the float valves is work smoothly. 5Install the defoaming tank
alarm system and put into operation as soon as possible,.

Seal oil temperature (keep oil temperature) , Advice power plant
owner to adjust temperature of generator operation oil as low as possible which
according to the condition of vibration of generator.
2.
Check liquid leakage detection device have oil leakage phenomenon. If find there
much oil leakage phenomenon, must ask power plant owner stop operation and find
result.

Exhaust the air inside the Stator winding before run the generator
To prevent parallel rings gas blocking, take measures to exhaust the air inside the Stator
winding system during stator winding system flooding water. The Details according to the manual
book of stator cooling water system operation reference to second section of chapter one.
Strict accordance with the requirements of manual book only in that way can prevent the gas
blocking. All the measures you take to prevent the gas blocking which according to the
manual book not only used for run a new generator but also for either generator which have
let the cooling water in to the stator winding should take the measures to exhaust the air
