  "textContent": "A method and a controller for protecting an electrical distribution system are disclosed. The electrical distribution system comprises an electrical grid being electrically coupled to an electrical branch. The electrical branch comprises a plurality of switches for connecting or disconnecting the electrical branch at respective positions on the electrical branch, wherein a load is electrically coupled to a node on the electrical branch. The method comprises: detecting a fault occurrence on the electrical branch based on a monitored voltage and/or current of the electrical branch; limiting, based on the detecting a fault occurrence, a power flow from the node to the load; adjusting, based on the detecting a fault occurrence, a voltage and/or current on the electrical branch; determining a fault location based on the adjusted voltage and/or current on the electrical branch; and disconnecting a portion of the electrical distribution system based on the determined fault location.",
