【 摘 要 】

Transformers are sophisticated equipmentin the power system compared to other elements, andas such, they require a continuous monitoring anddiagnosis for safe and reliable operation. Theirimportance in the functionality of the power system ismultiple. Monitoring techniques are used to followtheir operational work and consistency. There shouldbe listed monitoring and testing methods, collectiondata, parameters, failures and outage statistics,electrical and thermal parameter status, anddiagnosis for determining their operatingperformance. Based on case analysis according toloads of the power system, a load of transformers andnetwork topology are discussed regarding the results.In this case, are taken into account the networktopology of the Kosovo Transmission System, failurestatistics, failure effects and reliability indices. Themodel and simulation cases are performed with theNEPLAN software. These models also illustrate thecost of a failure modes in the power transformers inthe different scenarios.
