LIU Zhong-zhan. Research on Self-excitation Power Supply from High Voltage side of Electronic Current Transformers[J]. High voltageapparatus, 2006, (1): 55-57.DOI:
the electronic current transformer structure with getting power supply directly from high-volt-age-line is introduced. Several problems and countermeasures about the design of ’self-excitation power supply’ are discussed. The ’funnel structure’ (limit current) in taking energy from magnetic field scheme is put forward
and the experimental results of the system are provided.
