Electrical Preventive Maintenance and Checklist #electrical #maintenance #checklist

Post 2/2- Shutdown Maintenance (Electrical)   Key Learnings -Electrical Safety emphasizes the need for job detailing, team engagement, skill development, innovation and procedural compliance-.There must be a well-defined way of doing everything & right tool for the right job. -Make no assumptions; Avoid making assumptions regarding available spares, skills, quality, procedural availability & conformity, or safety measures. -All electrical control set points must be verified/ reviewed for transient conditions. These can be validated through transient stability study. -Generator Rotor Bolts must be inspected during Level-1&2 maintenance through borescope or other NDT techniques during Level-4 maintenance for cracks and corrosion. This can be caused by ozone formation due to PD or moisture ingress. -Regularly document and log as-built drawings, control system backups, and set point changes for effective change management. -Devise a model for verifying spares for Control Systems to manage surprises in firmware, OEM software availability, unprogrammed components, compatibility issues, and component health. Also ensure compliance, quality, and control of critical parts inventory (CPI) for all spares. -Test Differential protection for generators and verify protection relays ( positive testing) after modifications to avoid issues with logics, CT polarities, and connections. -Periodically test and replace Surge capacitors and arresters at the medium voltage level after certain breaker operations. -Account for DC Battery inrush during simultaneous breaker operation on power restoration and UV tripping on medium voltage breakers at black-out. -Thoroughly review synchronization band settings for all Power sources, incomer breakers, and bus ties.

🌟💡 Exceeding Expectations with Specialized Expertise in I&C and Electrical Work 💡🌟 At Gulf Turbine Services, we pride ourselves on our unique approach to instrumentation, controls, and electrical (I&C&E) work, setting us apart from standard electrical contractors. Our dedication is exemplified in the meticulous work of Felipe Rodriguez, who is currently focused on thermocouple assemblies on a gas turbine casing. This image captures more than just a moment; it highlights the depth of expertise and comprehensive understanding that GTS brings to every project. Why does having a specialty contractor with both I&C and electrical, commissioning experience, and a deep understanding of turbine machinery matter? It's all about ensuring a smooth startup and operational reliability. From taking ambient readings of thermocouples at disassembly to identify potential issues beforehand, to double-checking all terminations at every junction from PEECC, marshalling cabinets, and field devices, our approach is thorough and proactive. We go beyond the basics by verifying conduit runs and innovating maintenance-friendly solutions for disassembly and reassembly—a consideration often overlooked in new construction by EPC contractors. Adjustments such as implementing 3-piece unions, constructing sturdier conduit trees with hard pipe, and ensuring all fittings are up to code, particularly in gas turbine enclosures requiring class 1 div 2 fittings, are just a few examples of our commitment to excellence. Our dedication to detail extends to ensuring explosion-proof drains and properly poured seal offs, showcasing the extensive measures we take to not just meet but exceed safety and efficiency standards. By coordinating with scaffold contractors to build necessary structures ahead of time, from instrument storage to access work areas, we emphasize our proactive stance. This foresight allows us to push the schedule forward, maintaining self-sufficiency and staying ahead of potential challenges. At GTS, it's not just about doing the job—it's about doing it right, with an eye for detail and a vision for the future. Our team's expertise in both the micro and macro aspects of turbine maintenance ensures that we are not just contractors; we are your partners in achieving operational excellence. #GulfTurbineServices #ICandE #TurbineMaintenance #OperationalExcellence #ProactiveSolutions
