Field Simulation Method for Secondary Signal of Zero-Flux Current Transformer

The zero-flux current transformer is the most important sampling channel for the HVDC control protection system. The measured data is the most critical information and reliable evidence for the control, protection and measurement of HVDC. The field simulation method for secondary signal of zero-flux current transformer is lacking. This paper proposed a novel field simulation method for secondary signal of zero-flux current transformer. It can meet the need of zero-flux current transformer sampling channel testing in the accuracy and width for controlling and protecting. Its validity was verified by field simulation testing
