Study on Online Loss Measurement Technology for Distribution Transformers
No-load loss and short-circuit loss are important performance parameters of transformers.By measuring no-load loss and short-circuit loss of transformers,potential faults can be predicted in a timely manner to ensure their safe and sta-ble operation.Nowadays,in the context of"dual carbon"goals,transformers have great energy-saving potential.Timely detection and comprehensive treatment of high-loss transformers are of great significance for energy conservation,allevia-ting power shortages,and protecting the environment.This paper mainly studies the online measurement method of trans-former losses under operating conditions,which can satisfy the demand for real-time and efficient measurement of losses,promptly predict potential faults,and determine whether the transformers have acceptable operating efficiency according to national standards.
