Remarkable life cycle management by effective condition monitoring and assessment system of power transformer in CLP power system

Abstract

Effective power transformer condition monitoring and assessment system requires a great variety of state-of-art technologies to be applied for supporting a remarkable life cycle management in power networks. Power transformers are usually very reliable and durable components of the power generation, transmission and distribution networks. Their performance is often taken for granted and they are overlooked until a problem occurs. Unfortunately, when a fault occurs in a transformer, the result can be catastrophic and the failures are usually very expensive as it often results in the loss of the most expensive plant item in a substation if the power transformer is not uneconomical to repair. Cost of resulting loss in generation or transmission restraints is occurred until a replacement comes into effect. Clearly, despite the high reliability of power transformers, in view of the serious consequences of failures, it is important to employ an effective condition assessment system under smart grid operations so that faults can be detected at an early stage in order to improve the prospects for repairs and minimize the impact of any failures, under more optimization of operations.
