Abstract :
The structure design and optimization of printed-circuit board Rogowski coil (PCBRC) used to highly accurate measurement of alternative current are discussed in detail in this paper. The performance tests of PCBRC show that PCBRC are of excellent linearity, temperature characteristic and rejection of EMI, and can achieve 0.1 or 0.2 s accuracy class (IEC60044-8 standard). It can fulfill the demands of energy measurement in power systems.
