<p>An energy supply device (100) with connection means (106, 107) for an energy source (105) and an energy consumer (120). The energy supply device (100) is arranged to feed energy from an energy source (105) to an energy consumer (120), and (100) also comprises energy storage means (110) for supplying a connected energy consumer (120) with energy in the event of an interruption of energy supply. There is also a control unit (125) and sensing means (115) for sensing an energy flow to and/or from the energy storage means (110). The sensing means (115) are connected to the control unit (125) which detects a power disturbance if there is an energy flow from the energy storage means (115) during a predefined length of time.</p> |
