Test Item |
Procedure |
Criterion |
Remarks |
|
|
1 |
Temperature Rise Test |
The generator will be operated with rated current by equivalent loading method of IEEE 115 or zero(0) power factor method. Temperature rise of each winding will be measured by resistance method. |
Stator : <104oCRotor : <109oC |
Only one(1) set per ship *Cooling Water Temp = 36 C |
|
|
2 |
Over load Test |
The generator will have to withstand 50% excess of rated current for 30 seconds after temperature rise test. |
Without damage visually |
Only one(1) set per ship |
|
|
3 |
Over speed Test |
Over speed test will be carried out for 120 seconds with 1.2 times the rated speed under no excitation condition. |
Without damage visually |
|
|
|
4 |
High Voltage Test |
The test voltage with commercial frequency will be applied to each winding for 60 seconds. |
Stator : 2,000 V Rotor : 1,500 V |
|
|
|
5 |
Measurement of Insulation Resistance |
Insulation resistance of each separate winding will be measured with DC megger before and after high voltage test. |
More than 5 ㏁ |
|
|
|
6 |
Measurement of Winding Resistance |
Each winding resistance will be measured by bridge method. |
|
Only one(1) set per ship |
|
|
|
|
|
|
|
|
|
Above test items & procedure are satisfied with. (Machines having rated output more than 1,300kVA and using air cooler )
