Abstract
This paper presents frequency response characteristics of a Rogowski coil which is developed with an active integrator. Experiments are performed in a laboratory with a frequency function generator as a source. The frequency responses of the Rogowski coil and the integrator are recorded with both magnitude and phase in order to verify the capability in measur-ing lightning current waveshapes. For availability in lightning current measurement in the electrical sys-tem, the developed Rogowski coil is specifically de-signed as a clamp on device. The standard lightning current waveshape of the positive first stroke impulse (10/350 µs) is simulated to investigate the measur-ing system. It is found that the frequency bandwidth of the Rogowski coil with the integrator developed in this paper is proper in lightning current measure-ment.
