Suitability of Rogowski coil for DC shipboard protection

The achievements made in the field of DC shipboard power systems over the past decade have been impressive. However, the widespread acceptance of DC shipboard power systems is still hindered by the difficulty in ensuring protection of the system. One of the challenges in designing the protection systems is the selection of current sensors. This paper aims to study the suitability of Rogowski coil for use in DC shipboard power system protection relays. This paper describes the design and implementation issues of the Rogowski coil. It is shown that the geometrical orientation of the Rogowski coil has a major impact on the measurement sensitivity of fault currents.NRF (Natl Research Foundation, S’pore)Accepted versio
