Power Management & Protection

Backup power, protection and monitoring — units that protect the electrical system

A platform's electrical system is more than distribution. Backup power after engine shutdown, protection against wrong connections and line monitoring each need their own engineering. This category brings together the units that protect and monitor the platform's electrical system.
