Journal Article
Jia, K., Bi, T., Liu, B., Christopher, E., Thomas, D. W., & Sumner, M. (2015). Marine power distribution system fault location using a portable injection unit. IEEE Transactions on Power Delivery, 30(2), https://doi.org/10.1109/TPWRD.2014.2364259

A portable injection unit for Active Impedance Estimation (AIE) is built and tested in a DC zonal marine power distribution system to provide useful information for system protection and restoration. The portable unit generates current “spikes” and i... Read More about Marine power distribution system fault location using a portable injection unit.

A new Active Impedance Estimation (AIE) based protection strategy which is suitable for utilization in a DC zonal marine power distribution system is presented. This method uses two triangular current "spikes" injections for system impedance estimati... Read More about Advanced DC zonal marine power system protection.
