How To Judge Quality Do Test Generator Alternator Stator Analysis WIND-DTS-120

Testing item:

In generator staotr manufacturing, testing is the quality checking process after

paper inserting, wave winding, coil inserting, forming,

all the testing items including DC resistance/Inductance/Turn to turn insulaiton/ Insulation resistance

/Interphase insulation/Interphase Hipot/ Hi Pot/ Balance ofresitatnce can be conducted alone or together.

1)DC resistance test

Testing range:0.01W - 1000W

Testing loop:6 loop(scalable)

Tolerance:±0.5 %

Testing method:Four points, with auto ambient temperature correction function

2)Inductance test(including 3 phase balance test)

Testing range:10mH – 500mH

Testing loop:6 loop(scalable)

Tolerance: ±2.5%

Testing method:Four points

3)Turn to turn insulation

Pulse high voltage: 100V-3000V (100V / step)

Pulse peak: 0.5msec

Sampling frequency: 1-40 MHZ

Testing loop:6 loop(scalable)

Tolerance: ±2.5%

Judging method: area difference judgment (sensitive to inductance and energy loss)

Standard waveform is White,OK waveform is Green, NG waveform is Red

4)Insulation resistance

Voltage:DC500V /1000V

Testing time:1-10s(adjustable)

Judging range:1-1000 MW

Tolerance: ±2.5%

5)Interphase insulation

Voltage:DC500V /1000V

Testing time:1-10s(adjustable)

Judging range:1-1000 MW

Tolerance: ±2.5%

6)Interphase hipot

Voltage:AC100-3000V (100V/step)

Testing time:1-10s(adjustable)

Judging range:0.1 mA -- 20 mA

Tolerance: ±2.5%

7)Hipot(with arc detection)

Voltage:AC100-3000V (100V/step)

Testing time:1-10s(adjustable)

Judging range:0.1 mA -- 20 mA

Tolerance: ±2.5%

8)Balance of resistance

Test method: DC resistance sampling

Testing time:0.1s

Judging method:percentage method adopted to judge the difference of DC resistance between windings.
