Summary:There is provided a protection apparatus for protecting an electrical network (20). The protection apparatus comprises: at least one protection device configured to protect the electrical network from a fault in response to a or a respective protection criterion being met; and a controller (34, 36) configured to: receive real-time information on a change in topological structure of the electrical network (20); perform an online determination of the real-time impedance or admittance matrix of the electrical network (20) based on the change in topological structure of the electrical network (20); and adapt the or each protection criterion based on the real-time impedance or admittance matrix.
