The high-power demands of future ships has the US Navy moving towards Medium Voltage Direct Current (MVDC) architecture to power propulsion, sensors, and weapons. This requires knowledge of clearance and creepage distances for insulation in shipboard power systems, which is currently only partially known and understood. The project investigates breakdown mechanisms in shipboard power insulation under different conditions such as insulation contamination system fault, at medium voltage DC, which enables accurate calculation of clearance and creepage distances.
