A common challenge to today’s utility engineers is to extend the life of existing power delivery assets through better understanding of asset condition and operational issues that significantly impact the remaining asset life, and implementation of maintenance practices to support operating objectives.
Quanta Technology’s Asset Management Program optimizes your company’s investments and spending. We have identified the critical elements for successful management of your utility’s asset base, while balancing cost, performance and risk in order to meet multiple business goals.
Today’s utilities expect higher reliability, lower costs and increased earnings. Addressing aging electrical and structural infrastructure is challenging with traditional budgeting processes. Quanta Technology’s Asset Management Program experts can evaluate the condition of major power delivery assets, such as power transformers, circuit breakers and other substation infrastructure to assist in your decisions around capital equipment operations, refurbishment and replacement. Comprehensive evaluation and testing of existing equipment can be conducted to quantify current risks of continued operation and to assist you developing a comprehensive equipment maintenance strategy. Our services include:
Transformer Analysis – Perform comprehensive analysis of operating and test data on transformers to provide information on the remaining life of the unit, as well as any imminent risk of failure. Loss-of-life calculations, based on various test results and performed in compliance with IEEE standard C57.91-1995, can provide information on remaining insulation life and assess the overall transformer condition and loading capability.
Predictive field tests for comprehensive loading and failure risk analyses include:
- Visual inspection
- Ultrasonic/partial discharge analysis
- Vibration analysis of main tanks and pumps
- Infrared thermography
- Acoustic emission and noise analysis
- Cooling system analysis
Maintenance Management – Develop more efficient programs based on equipment condition, age, duty and other operational factors to ensure reliability targets with optimal service intervals, achieving significant operational savings over traditional time-based maintenance programs.
EXTREME WEATHER HARDENING
Quanta Technology has helped dozens of utilities address nearly every aspect of this complicated subject, including improvements to system protection, emergency switching, vegetation management and applications of emerging Smart Grid technologies. We tailor our services to meet your specific needs.
We meet increasing expectations to "harden" the energy delivery system to be more resilient to weather events, such as hurricanes, wind and ice storms. Typical engagements include:
System Hardening – Assess and improve vegetation management, pole strength, pole loading, small wire and underground conversion, and other measures in a cost effective manner, including development of a short-term plan to address critical issues and a long-term roadmap to systematically address the entire system over time.
System Resiliency – Improve the design, operation and control of the power delivery system to allow quicker restoration and minimize customer interruption-minutes through better line switching, automation technology, right-of-way access, restoration sequencing, inventory and contractor management, etc.
Storm Response – Improve actual storm restoration efforts by more effective usage of storm centers, outage management system, mobile dispatch and field force automation for damage assessment and forensic data collection; improved internal and external communications; better logistic support, supply and contractor management, etc., in addition to post-storm auditing support.
Storm Modeling – System modeling to estimate the type, amount and locations of damages as a storm approaches, so that crews can be stocked and pre-dispatched. Quanta Technology leads the industry in applying storm modeling to improve system hardening, system resiliency and storm response plans.
Finally, justification can often be a very important aspect of a project or budget to stakeholders, customers and regulators. Quanta Technology’s expertise provides a quantified and comprehensive plan to suit your needs.
