Abstract

In the U.S. navy´s transition to an all-electric ship, system designers must take great care to ensure that critical design choices provide highly reliable and safe power system operation and protection during all mission scenarios. Transitioning from low voltage (450 V/sub AC/) radial configurations to medium voltage (13.8 kV/sub AC/) multi-source systems requires new naval protection schemes. This paper specifically analyzes methods for quickly determining ground faults in ungrounded and high-impedance grounded naval power systems.
