Abstract

In a line to line fault detection and protection system, a source end power supply supplies power to a remote load over a transmission line and monitors the dynamic behavior of a transmission line power characteristic. If that dynamic behavior is outside a constraint that is actively imposed on the transmission line dynamic behavior by a load end power conditioning system, a possible line to line fault is recognized. The preferred power characteristic is current and the preferred constraint is a maximum rate of change of current drawn from the transmission line by the load end power conditioning system.
