Reverse Power Protection (rPmax)

Reverse Power Protection

Reverse power protection protects alternators against absorption of the total actual power over all three phases in the event that a drive motor fails.

  • Reverse power protection applies a trip curve based on the total actual power value (A) over all three phases.

  • A time delay (B) starts timing if the total actual power of the three phases is not flowing in the defined direction and if it exceeds a reverse power threshold.

  • The power direction is defined during trip unit setup.
