According to the GE manual, maintaining a consistent ground on the Generator Hydrogen seal insulator or bearing insulator may lead to pitting of the generator bearings. The manual suggests conducting inspections on these insulators every 3-6 months using a voltmeter or meggar. We are interested in finding out if any facilities have implemented automated monitoring for continuous insulation checks, with real-time data sent to the DCS for visualization and alarm notifications.
Is there a cost associated with automation? If the cost is minimal, then it would be beneficial to proceed with automating the process. This will allow the electrician to focus on other preventive maintenance tasks, ultimately saving time and increasing efficiency.
Yes, that's a solid point. We have actually implemented an automated insulation monitoring system at our facility. It essentially involves the use of smart sensors and IoT tech, providing us with continuous and real-time data to detect any insufficient insulation. It has improved our ability to schedule necessary maintenance work proactively rather than reactively. We've definitely seen a decrease in unexpected generator breakdown and the associated costs since including this system in our set-up. It's certainly worth considering if you're looking to mitigate the risk of damaging generator bearings due to inconsistent grounds.
In our facility, we have successfully implemented an automated monitoring system for the generator's insulation checks. The system uses voltage and resistance sensors which are directly connected to the insulators. This configuration provides real-time data to our Digital Control System (DCS), which not only visualizes the information but also triggers alarms for any anomalies. This has greatly reduced our burden of manual inspections and enhanced the precision levels. However, we still conduct a thorough manual check semi-annually to ensure nothing is missed. The fusion of automation with manual checks, in our experience, gives the best reliability in operation.
