摘要： The present invention relates to an apparatus for connection between power transmission system field equipment and control and protection equipment and comprising at least one input/output module (24). The module (24) comprises a box (34) enclosing a circuit board with at least one signal handling unit, at least one bus connector (36, 38) that stretches through a first side of the box, and a set of terminal blocks (40) for connection of field wires to the field equipment, where the terminal blocks are placed on a second side of the box. The at least one signal handling unit includes at least one unit for conversion of input and output signals to and from the field equipment and bus communication according to a bus communication protocol.

摘要： A method and apparatus for determining the time of arrival of a fault wave at a measurement point of a power transmission system includes a measurement unit measuring a power quantity of the system at the measurement point (P1) for obtaining a measurement quantity being a potential fault wave, a time keeping unit, a storage unit storing the measurement quantity, a comparing unit comparing the measurement quantity with a threshold (T1) for detecting the presence of a fault wave (W1) and an analyzing unit. The analyzing unit analyzes measurements made before the fault wave presence was detected, determines the starting point (SP) of the fault wave based on the analysis and sets the time of the starting point to be the fault wave arrival time (T1).
