Abstract :
- The need to improve asset management
frameworks has been a major concern among industrial
consumers in Uganda. Poor asset management increases
frequency of faults among industrial consumers thus
resulting into poor quality of power supplied. This
research was developed based on the fact that cases of
cascaded failures in connected systems have rampantly
increased among industrial consumers in Kawempe
Industrial Area. This has been due to factors such as
proliferation of substandard circuit breakers,
malfunctioning of circuit breaker components, external
conditions that affect circuit breaker performance such
as temperature, dust, etc., and negligence in conduction
of compliance tests among others. These factors have
not been put into consideration for the sake of effective
asset management. Prior to implementation of an
effective asset management framework, there is need
for diagnosis of the present factors that hamper
effective asset management and develop replacement
strategies. This paper focused on Circuit Breakers
(CBs) since they consume a large proportion of budgets
of maintenance of utilities and are critical to system
reliability. The parameters influencing CB performance
were determined by Weibull modeling in MATLAB
2018: findings revealed that the industrial CBs had a
maximum hazard rate of 5.6% with an average mean
time-to-failure of 13.47 years, which represents a high
propensity to death and critical condition of all CBs.
