    摘要： The invention relates to a protective circuit (1) for protecting against overheating of the stator windings (U, V, W) of an EC motor (M), which are connected to a semiconductor output stage (2) and which are designed for the time-offset control of the stator windings (U, V, W) of the motor (M) by means of a driver circuit (7) of an electronic commutation controller for the purpose of a producing a rotating magnetic field, characterized in that the protective circuit (1) is designed having two redundant sensor circuits (10, 20), wherein two resistance-dependent sensor elements (11, 12) connected in series are provided in the first sensor circuit (10) and one resistance-dependent sensor element (21) is provided in the second sensor circuit (20), wherein the first and the second sensor circuits (10) are connected, respectively, to two evaluating circuits (30, 31) and (40, 41) separated from each other, which effect an interruption of the driver circuit (7) preferably by means of switch-off means when a system-specific limit resistance value of the sensor element (11, 12) or (21) associated with the sensor circuit is reached, in order to thereby switch the stator windings (U, V, W) of the motor (M) to a currentless state.

    摘要： A digital protection control device 9 that acquires a bus voltage by using data from a protection control terminal 8 that converts a voltage detected by a voltage transformer 7 arranged on a plurality of lines 3, a state of a circuit breaker 4 arranged on each of the lines 3, and a state of a disconnector 5, 6 arranged on each of the lines 3 into digital data, includes a simulated-bus-voltage selecting unit that, on a basis of voltage data related to the voltage, data related to the state of the circuit breaker 4, and data related to the state of the disconnector 5, 6, selects the voltage data as a simulated bus voltage that is a simulated value of the bus voltage; and a synchronism indicator that detects whether the voltage data and the simulated bus voltage are in a synchronized state and outputs information C1 to Cn indicating a synchronized state to the protection control terminal 8.

    摘要： A system for detecting loss of an electrical phase in a compressor system includes a compressor system component (10) having a plurality of phase carrying legs (16, 18, 20) comprises a sensor (22) for measuring current communicated with one leg (18) of the plurality of phase carrying legs and a processor unit (24) adapted to receive a signal from the sensor (22) and determine whether loss of phase has occurred in any of the plurality of phase carrying legs (16, 18, 20).
