    Abstract: A voltage measurement device includes an insulating body, for the use in medium- or high-voltage equipment or switchgears The insulating body includes an impedance divider having at least one high voltage impedance and at least one low voltage impedance in series, and with shielding electrodes. In order to optimize the circuit design for voltage measurement design in a given application and prevent the risk of malfunction when the same device it is used in multiple applications or at severe environmental or operating conditions, the device includes at least one high-voltage shielding electrode and/or at least one low-voltage shielding electrode which dimensions together establish a physical length of the impedance divider. The shielding electrodes surround the high and/or low voltage impedances, which provide a specified voltage division ratio and which are located inside or outside of the insulating body. An output of the impedance divider is connected to a shielded cable.

    Abstract: A combined measuring and detection system is disclosed which includes an electronic evaluation unit for analyzing a broad frequency spectrum of measured quantities and one or more measuring devices for measurement of one or more of a magnetic field, an electric field, a current, and a voltage. The measuring devices are operatively connected to the electronic evaluation unit, which is provided with at least one frequency splitter dividing the measured quantities into a low frequency component and into a high frequency component. Low frequency components are used for measurement and protection analysis and high frequency components are used to detect partial discharges activity.

    Abstract: An exemplary voltage sensor device includes at least one high voltage segment and at least one low voltage impedance element. In order to enhance the power dissipation due to impedances spread inside of the device body, the sensor device can be adapted or extended such that at least one high voltage segment, and at least one low voltage impedance element are arranged on an elongated insulating support with adaptive complementary mechanical and electrical interconnection elements on at least one end of the support element. The mechanical and electrical interconnection elements provide a manner of interconnecting at least two elongated insulating supports together in a pivotable way.
