Introduction: Condition Based Risk Management of 50 High Voltage (HV) Transformers.

Objectives: The process known generically as CBRM has been developed as a result of EA Technology working with distribution and transmission companies. CBRM relies on the application of some basic principles and building, in each application, a systematic process to combine engineering knowledge, asset information and practical experience to define current and future condition, performance and risk. The ultimate aim is the provision of information to assist companies target investment to maintain a defined level of network performance at minimum cost without compromising on safety or environmental impact.

CBRM relies upon utilising the best available technical knowledge of assets, degradation processes, failure modes, condition assessment techniques and practical engineering experience. Successful application enhances a Network Operators ability to target investment (for asset replacement, refurbishment) and operational spending to achieve a defined level of performance. Thus impacting on the future performance and development of networks. This project will apply the methodology to a statistical sample of 50 132kV and 66kV transformers.
