Diagnostic Measurements for Power Transformers
With the increasing age of the primary equipment of the electrical grids there exists also an increasing need to know its internal condition. For this purpose, offand online diagnostic methods and systems for power transformers have been developed in recent years. Online monitoring is used continuously during operation and offers possibilities to record the relevant stresses which can affect th...
متن کاملCondition Monitoring Techniques of Power Transformers: A Review
Power transformers provide a vital link between the generation and distribution of produced energy. Such static equipment is subjected to abuse during operation in generation and distribution stations and leads to catastrophic failures. This paper reviewed the techniques in the field of condition monitoring of power transformers in recent years. Transformer monitoring and diagnosis are the effe...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Condition and risk assessment of power transformers: a general approach to calculate a Health Index
Power transformers are the most important assets in substations and play an important role in the reliability of electrical systems and in the quality of the energy delivered. As the population of transformers in service is getting old, much attention must be focused on transformers availability and reliability. So the condition and risk assessment of the transformers are more and more importan...
متن کاملGrey Relational Analysis for Insulation Condition Assessment of Power Transformers Based Upon Conventional Dielectric Response Measurement
Conventional dielectric response measurement techniques, for instance, recovery voltage measurement (RVM), frequency domain spectroscopy (FDS) and polarization–depolarization current (PDC) are effective nondestructive insulation monitoring techniques for oil-impregnated power transformers. Previous studies have focused mainly on some single type of dielectric measurement method. However, the co...
