CBRM

 

Equipment is generally designed for a certain economic service life and is dependent on operating environmental stress, effective maintenance program and the quality during manufacturing including proper installation. After, this estimated service life period equipment is not expected to provide operational reliability.

 

‘Condition Based Risk Management’s (CBRM) greatest strength is that it enables users to make more intelligent business decisions on the management of power plant and equipment. It is ultimately a financial planning and a network performance tool.’

 

Method we propose for Health Index (HI) is more detailed method and this pattern is adopted by leading utilities for 40 years old transformer of transmission unit. This approach is more practical as we can see the transformer condition on component level from maintenance point of view. Also it is easy to compare with sister unit and create a FEMA tree as TF has so many active accessories which are linked to its reliability and life assessment. It is not simple to evaluate life and reliability on the basis of paper aging.

 

Worldwide Major work in HI is done in MV TF which is different from HV and EHV class transformer and here we have an edge or benefit over other consultant with respect to skill and experience.

 

 

LA has worked with Utility in Power & Distribution sector on developing CBRM models for a range of asset groups. The models are however not integrated with each other, This results in high levels of expertise and provide consistent reporting of CBRM Health Indices and ageing & it has been divided into a number of stages:

  • CBRM for Transformers
  • CBRM for  HV & MV switchgears
  • CBRM for cables
