The company’s maintenance team enhanced the network reliability by applying new condition monitoring technology such as thermal scanning, partial discharge, and DGA to assess the asset condition. Using these techniques, the team manages to repair assets before it causes network outages.
Mazoon Electricity had adopted condition based risk management system (CBRM) for power transformers and high voltage switchgears to assess the health index of those assets in order to prioritise the maintenance and future investments.
Recent results of the CBRM module shows that most of the power transformers and switchgears are in good condition. Plans are on to add more to the module to have robust outputs of the CBRM in the future, said the statement.
