Abstract: A meter for recording or determining the electrical energy withdrawn from an electrical supply network or supplied to it is provided. The meter including a component for measuring the current supply voltage, and a component for determining the operating mode based on the currently withdrawn or supplied electrical energy, wherein the operating mode can be changed, depending on the measured supply voltage, in such a way that a relatively high supply voltage causes a slower metering process than a comparatively low supply voltage.

Abstract: A photovoltaic system having a photovoltaic generator, whose strings with series-connected photovoltaic modules have a positive pole and a negative pole, and with an inverter whose DC input is connected to the two poles. The voltage of the positive pole and/or of the negative pole is measured with respect to ground, and a first switching element located between the positive pole and the DC input of the inverter and/or a second switching element located between the negative pole and the DC input of the inverter is opened, while a third switching element located between the positive pole and the negative pole is closed, when the voltage of the positive pole or of the negative pole exceeds a predefined first or second limit value.

Abstract: During operation of at least one power generator (EE) in a power supply network, a reactive power transfer between the two upper voltage levels (1, 2) is sensed at a first transformer (T1) connecting these levels, and the voltage at a first network connection point (5) at the lowest voltage level (3) is ascertained. The amount of a reactive power demand served by the power generator (EE) is calculated as a function of the ascertained voltage value in order to maintain the voltage ascertained at the lowest voltage level (3) within a predefinable voltage range, wherein a means (WR) of the power generator (EE) is activated for a reactive power draw or a reactive power delivery, based on the calculated reactive power demand.
