Hello, I am seeking assistance with resolving a rotor earth fault issue in the Siemens V94.3 Gas Turbine and SGEN5-1000A 297 MVA generator installed at Chana Power Plant in Thailand for the past 4 years. Any insights or solutions to fix this problem would be greatly appreciated. Thank you.
Hello, it's important to inspect the controller card and investigate potential rotor insulation breakdown. It would also be helpful to know the age of your generator and whether any condition-based monitoring (CBM) has been conducted on the equipment. Thank you.
Hello Chana, there could be several factors contributing to this issue. One possible solution is to inspect the ventilation system in the room where the unit is located. Poor ventilation could be causing excess moisture due to the heat emitted from the unit into the surrounding area. Be sure to address any ventilation issues to prevent humidity build-up.
Hi there! Dealing with rotor earth faults can be quite tricky, especially in complex systems like the Siemens V94.3. I’d recommend starting with a thorough inspection of the insulation resistance and checking for any signs of wear or damage to the rotor windings or cables. Additionally, reviewing the grounding system and ensuring all connections are secure can sometimes reveal hidden issues. It might also be useful to check the manufacturer's guidelines for troubleshooting these specific faults, as they often have detailed diagnostics procedures. Good luck, and I hope you get it resolved soon!
Hi there! Dealing with rotor earth faults can be tricky, but I recommend starting with a thorough insulation resistance test to pinpoint any weaknesses in the rotor windings. Additionally, check for any signs of moisture or contaminants that could be causing issues. It could also be beneficial to review the turbine’s maintenance history and ensure all connections are tight and corrosion-free. If the problem persists, reaching out to Siemens for their expert advice or troubleshooting support might save you time. Good luck!
