Abstract

Rogowski coils are special types of mutual inductors often used to measure large alternating and transient currents. Traditional handmade Rogowski coils lack accuracy and cannot be easily mass-produced. Two new structures of Rogowski coils based on printed circuit board are presented. Theoretical analyses on the mutual inductances of two designs are discussed. The measurements of basic characteristics, linearity tests, frequency-response tests, temperature performance tests, and related positional sensitivity tests for the two new coils and traditional coil are carried out. The two new Rogowski coils are proved to have excellent accuracy and temperature performance and can be easily applied in mass production
