Transformer Rla And Online Screening Test

RESIDUAL LIFE ASSESSMENT (RLA)
In general, Transformer RLA such as Generator Transformers, Station Transformers and Inter-connecting Transformer are required to be highly reliable so that operational as well as safety risks at site are minimized. In order to ensure transformera s reliability, it is vital to assess the extent of ageing and early identification of emerging faults. We offer a suite of tests referred to as Residual Life Assessment which helps in assessing remaining useful life of a given transformer.

The RLA test program employs a selection of tests including electrical tests, oil-paper related tests to assess the insulation degradation as well as online Partial Discharge test on the transformer. Such tests reveal adequate information pertaining to insulation degradation and remaining life left.

This program has been designed with operational safety and reliability in mind. It allows the asset owners to take timely decisions to help resolve the issue by enacting necessary repairs, refurbishment or replacement.

ONLINE SCREENING OF LARGER ASSET BASE

A very detailed life assessment program is a thorough condition assessment tool for transformers. But there are instances where only condition screening is preferred, generally because of larger asset base and the total costs involved. We suggest a purposefully crafted an online screening program which employs minimal tests but still yields very useful and actionable information without stretching budget any furth
