Power distribution terminal capable of determining fault type and determination method thereof

An automation terminal for a power distribution network, disposed at a power distribution apparatus and used to monitor at least one incoming line and at least one outgoing line of the power distribution apparatus, the automation terminal comprising:

• a fault detection apparatus to, for each respective line amongst the at least one incoming line and the at least one outgoing line, record a number of faults which occur on each respective line;
• an automated reclosing detection apparatus, to determine a number of automated reclosing operations executed by a substation side associated with the power distribution apparatus on the basis of at least one of a current a voltage on each respective line;
• a fault determination apparatus to determine, for respective each line and within a fault type determination period, that a fault on the respective line is a permanent fault upon a number of faults occurring on the respective line being greater than a maximum number of automated reclosing operations permitted by the substation side, or upon the fault being a further fault;
• wherein the fault type determination period is a time period after the jth automated reclosing operation, where j is a natural number, j is greater than or equal to 1, and less than or equal to the maximum number of automated reclosing operations.
