Stator Water System Chemistry It is estimated that 40% of water based stator cooling systems operate with high–dissolved oxygen and neutral water chemistry. in this treatment regime, cuo is formed on the copper. Generator cooling water) generator cooling water system gcws closed cooling water system that removes the heat produced from the generator. it comprises the cooling of the stator as well as the rotor, if applicable. high oxygen treatment using water where the dissolved oxygen level is kept high, usually near saturation.
Stator Water System Chemistry Ppt Monitoring chemistry parameters a)dissolve oxygen: measurement of do is required for maintaining as per the respective treatment system. measurement of do in stator water also affords valuable information about hydrogen leakage through stator tiny h2 leakage non detectable through h2 gas trap or consumption pattern leads to lowering of do content of stator water b) ph: measurement of ph. Guide on stator water chemistry management 0 1 0 2 l i r p a 1 study committee a1, wg a1.15 page 6 of 22 2.2 mechanism of plugging under the conditions typically found in pure water systems, copper does not react with water in the absence of oxygen [8]. in practice, however, oxygen is in many cases introduced into a generator. Int erp ret ati on of s tat or c ool ing w ate r chemist ry data. abstrac t. key parameters for chemistry monitoring of stator cooling water are conductivity, electrochemical potential (ecp), ph. By the system water chemistry. figure 4 gives examples of a specimen with dense polyhedral oxides, typical for high oxygen or alkaline water chemistry, and another one with flower shaped needles, typical for low oxygen or neutral water chemistry. coupon samples in a generator stator cooling system verified these results. figure 3:.
