Abstract: An electrical assembly comprising a housing (2), a power supply (6) adapted to supply power to a load means, the power supply (6) being located inside the housing (2), a sensor means (8) adapted to detect conditions inside the housing (2), the conditions comprising humidity and/or temperature, and a control means (CTRL) adapted to control the power supply (6). The control means (CTRL) is adapted to receive information from the sensor means (8), and to perform at least one humidity prevention action in a predetermined humidity situation detected based on the information received from the sensor means (8). The at least one humidity prevention action comprises turning on the power supply (6) when a predetermined humidity situation occurs while the power supply (6) is in off state.

Abstract: A method of estimating DC-link capacitance of a converter assembly, the converter assembly comprising a converter (EC) adapted to convert electric energy from one form to another, the converter (EC) has a first power connection (T1) which is a direct current connection, and a second power connection (T2), and a DC-link capacitor (C1) operationally connected to the first power connection (T1) of the converter (EC). The method comprises determining an initial voltage (u C1_t0 ) of the DC-link capacitor (C1), effecting a voltage change of the DC-link capacitor (C1) in order to alter charge of the DC-link capacitor (C1), determining a final voltage (u C1_t1 ) of the DC-link capacitor (C1), and calculating a capacitance (C C1 ) of the DC-link capacitor (C1) using the initial voltage (u C1_t0 ) and final voltage (u C1_t1 ) of the DC-link capacitor (C1) and energy transition required for the voltage change of the DC-link capacitor (C1).
