Abstract: Apparatus includes an arc wave generator for testing an arc fault circuit interrupter (AFCI) for use in a test system for testing whether or not an arc fault circuit interrupter (AFCI) is operating normally, in which a false arc is generated for use in testing the arc fault circuit interrupter (AFCI). The arc wave generator includes a rectifier which receives a commercial power source as an input source and rectifies alternating-current voltage of the commercial power source to generate a rectified signal. A drop resistor drops the voltage of the rectified signal to generate a voltage-dropped signal. A mono-stable multivibrator adjusts a voltage level and a pulse width of the voltage-dropped signal and generates a pulse signal which is used to generate a false arc for testing the arc fault circuit interrupter (AFCI). Thus, a false arc is generated with a simple circuit to accurately test the actions of the arc fault circuit interrupter (AFCI).

Abstract: According to the method a temperature module is defined, simulating the thermal behavior in the electric motor (1), based on a multi-mass model. The rotational speed (n) and the current (i) for the electric motor (1) are continuously recorded as input parameters for the temperature model and at least one bearing power loss and/or bearing inner temperature (TIL1?), corresponding to a bearing (8,9), is continuously derived from the temperature model. A first warning signal (W1) is given when a computer-determined bearing power loss exceeds a given comparative value. Furthermore, a second warning signal (W2) is given when a computer-determined bearing inner ring temperature exceeds a given temperature difference (?T) from a corresponding computed bearing outer ring temperature (TAL1?). The thermal behavior of non-accessible components, in particular, the bearing (8, 9), can thus advantageously be determined by mere evaluation of the current (i) and the rotational speed (n).
