Abstract

The invention relates to a voltage measurement device with an insulating body, for the use in medium or high voltage equipment or switchgears, with an impedance divider consisting of at least one high voltage impedance and at least one low voltage impedance in series, and with shielding electrodes, according to the preamble of claim1. In order to do optimized voltage measurement design for a given application, preventing risk of malfunctionality in case the same device it is used in other application or at severe environmental or operating conditions, at least one high voltage shielding electrode and/or at least one low voltage shielding electrode which dimensions are applied to the physical length of the impedances, and that the shielding electrodes sourround the high and/or low voltage impedances providing required voltage division ratio, and which are located either inside or outside of the insulating body in order to distribute the electric field in the best way to reduce electric field stress either inside or outside of the said device, and that the output of the impedance divider is connected to a shielded cable, which is also part of this device.
