摘要： An impedance matching element is disclosed which can be used for voltage and/or current sensing or indicating devices used in medium voltage systems in order to improve signal integrity of output signals in comparison with known sensing devices. To enhance sensing accuracy and provide higher output signal immunity against interferences and impedance mismatches, the electric field sensor and/or the magnetic field sensor can be connected to the impedance matching element which allows connection to an independent analog measuring device and is powered from an energy harvester, with an impedance matching electronic board.

摘要： 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.
