Improve plant reliability and enhance operational performance
Critical electrical asset reliability is a cornerstone of the power generation and industry’s drive for safe and reliable plant operations. Whether nuclear, steam, hydro, combined cycle, simple cycle, diesel, renewable generation or industrial, rotating machinery condition assessment services from Doble provide a solid foundation for effective condition-based maintenance programs based on industry best practices.
Doble is the trusted, independent rotating machinery condition assessment expert, providing on-line and off-line diagnostic service solutions to improve plant reliability, enhance operational performance and enable limited maintenance budgets to be targeted toward critical and/or problematic units.
On-line generator/motor assessment solutions include:
- EMI Diagnostics testing
- Partial discharge testing
Off-line generator/motor testing solutions include:
- Visual inspection
- DC insulation resistance and polarization index
- AC power factor and capacitance
- AC partial discharge
- Air gap search coils
