Generator Stator cooling water conductivity question

Generator Stator cooling water conductivity question

Generator Stator cooling water conductivity question

(OP)
For Demin water stator cooling system
Why is the conductivity lower coming back from the generator then going to the generator.
Going to gen after HX and IX is about 0.13 micro Siemen/cm
Coming back from gen is about 0.5 micro Siemen/cm

Temp coming back is about 60 degree C
Temp going to gen is about 47 degree C

Original post had an error

I meant to say coming back from generator it is about 0.05 micro Siemen/cm

 

RE: Generator Stator cooling water conductivity question

You may have dissolved copper passing through your mixed bed.

'It is important to remember that the major cause of problems in stator cooling systems has not been corrosion per se but, rather, deposit accumulation in critical areas. These deposits are copper oxides released from one area of the stator coolers and deposited in another. The amount of dissolved oxygen in the system, and particularly variations in that oxygen concentration, determines when copper oxides are released.'

Why don't you get a water analysis of both waters?
