摘要： The present invention relates to a method, device and computer program product for determining at least one property of a current (I p ) running through the primary winding of a transformer operating in saturation using an unreliable detected current (I s ) running through the secondary winding of the transformer. According to the invention a first reliable extreme point (EP1) of a cycle of the current in the secondary winding is detected and compared with an absolute time reference. Based on the comparison a first property of the current running through the primary winding in the form of the phase angle is then determined.

摘要： A transmission for a vehicle comprises a mechanical stepped gearbox (6) in front of which a hydraulic torque converter (5) is arranged. The torque converter (5) comprises a turbine wheel (19) which is connected to a turbine shaft (21). An input shaft (25) of the gearbox (6) is connected in a drive power-transmitting manner to the turbine shaft (21). In addition, a brake (34) is connected to the turbine shaft (21) or the input shaft (25), in which respect, on starting-up, the input shaft (25) can be stopped in order to permit engagement of a starting gear without the need to produce drive power interruption by means of a conventional clutch. The brake (34) is also used when changing-up for synchronisation of the gearbox (6) together with an electrical control unit (32) for engine regulation. This allows the gear-changing in a mechanical, unsynchronised stepped gearbox to be carried out in a simple manner.

摘要： The invention concerns a method and computer program product for determining the direction of fault in an electrical power system as well as to a fault handling device. In the fault handling device the voltage at a measurement node of the power system is measured, the phase (Φ PF ) of this voltage (V PF ) before a fault is stored, the phase (Φ F ) of this voltage (V F ) at the end of a time interval (TI) following directly after a detected fault is determined, a phase offset (ΦO) is determined as the difference between the phase (Φ PF ) of the measured voltage (V PF ) before the fault and the phase (Φ F ) of the measured voltage (V F ) at the end of the time interval (TI) and the phase (Φ F ) of the measured voltage (V F ) after the detection of the fault is adjusted with the phase offset (Φ O ). Thereafter the adjusted measured voltage is used in determining the direction of fault in relation to the measurement node.
