wcaseyharman (Electrical) Further to your reply in above thread. for 300 MW Steam turbine Generator; We plan for 3 CTs for each phase on line side (total 9 CTs) 3 CTS for each phase on neutral side (total 9 CTs) Now customer is asking to keep 3 CTs for each phase on line side (total 9 CTs) 4...

I have general question. On Steam turbine LP section, I have typically seen rupture discs for the protection from the over pressurization. In a new project, ACC, Air Cooled Condenser supplier is providing Rupture discs covering the Steam turbine LP portion volume as well. In this case, can we...

wcaseyharman (Electrical) Thank you for your helpful feedback and sharing knowledge.

wcaseyharman (Electrical) Thanks. We are in the early design phase with the Generator supplier so protection and metering design is not done. I am not Generator/Elect. expert. So can anyone advise me best way to proceed, i.e. how many Total CTs on line side(per phase) and how many Total CTs on...

cranky108 (Electrical Thanks. wcaseyharman (Electrical) Thanks. stevenal (Electrical) Thanks. 3 CTs per each phase so total 9 for line side. Same way 3CTs per each phase on Neutral side so total 9 for Neutral side. edison123 (Electrical). Thanks. You replied as "Normal set up is one line CT...

For a large Steam turbine Generator (300 MW class), any preference for dedicated current transformers for each phase vs multi core current transformers? i.e. One multi core CT on line and One multi core on Neutral side vs 9 on line side and 9 on Neutral side. Any suggestion? Thanks in advance !

I have a question about Steam turbine performance test code (ASME PTC 6 vs DIN1943). I am not familiar with DIN. We do not have contractual requirement to follow one over the other. 1.If OEM prefers DIN, would it be possible to accept? what are the fundamental difference and risk vs benefit...

Gr8blu (Electrical) Thanks a lot again

Gr8blu (Electrical Thanks a lot.

Hello Any tips to prevent potential water leak to Air circuit in TEWAC (Totally Enclosed Water Air Cooler) Turbine Generator? Having only one leak detector in the heat exchanger is reliable? Thanks in advance !

I have a quick question regarding scope of Vacuum breaker valve. who should be technically providing it? Steam turbine supplier or Condenser supplier? and what is the reason for that? Thanks in advance

Hello, In our project location (Middle east)considering higher ambient in summer (52 C) and in fact very limited water availability, I am considering Dry cooling heat exchanger. I have to meet closed cooling demin. water temperature Max at 45 C at Max ambient 52 C. 1. Can I achieve this with...

LittleInch Thanks. I have not sourced any information so far. I am looking for general information regarding which type (A frame vs W frame) better ? e.g. better performance, easy installation, etc.

I would like to know A frame vs W frame Air cooled condenser (ACC) brief comparison for selection purpose considering performance and cost effectiveness. Thanks in advance.

jsteng123 Thanks. Yes some countries does not require code stamp. So in your case, did authority in Columbia accept vessels based on previous version?

GD2 Thanks, we are not manufacturer. P/V was not U stamped because it was not mandatory in that project which got cancelled.

*subqa* Thanks with great feedback. P/V not U stamped (but U certified) and most likely not required to stamp in new project.

*The Obturator* Thanks for your feedback.

I have a situation where Project was in Mexico o U stamp is not required so pressure vessel(P/V) is ASME U certified but without U stamp. This was ASME edition 2017. This project got cancelled so P/V is in storage. Now we found new project site in Mexico and we have an agreement in contract with...
