Conducted technical evaluations of engineering designs and test results.
In Plant Performance: SAIDI & SAIFI, Investigation of root cause for equipment failure, QA, populating data on excel. Transformers are very important in power transmission and distribution systems, and their operational stability impacts the reliability and operating cost of the grid system Transformers are intended to last for a certain amount of time. According to the standard 240-146 444 193, Eskom distribution transformers are expected to last at least 25 years Failing to attain that life span is a concern that has made transformer failures a major issue Distribution Transformers are the most expensive equipment of 8-line components (Trfr, Fuse, Isolator, Pole, Conductor, Insulator, Jumper, Transient) and they have a major effect on SAIDI due to their lengthy restoration time The 8-line components contribute about 90% of the System Average Interruption Duration Index (SAIDI) Although research on distribution transformer failures has been conducted recently, these failures continue to be an issue in the KZNOU.
In CNC: Fault finding, monthly inspection on the network and substation.
