    • The voltage sensor for measurement of a voltage V, which is present between two electrodes (3, 4) and generates an electric field E, comprises at least two layers (1a, 2a) made of electro-optically active material and being arranged along a light path (5). Through the layers there passes a light beam, the phase and/or state of polarization of which is influenced on account of the electro-optical effect. The orientation of the electro-optically active layers (1a, 2a) relative to the light path and the electric field E is chosen in such a way, that the influencing of the light (5) in the second layer (2a) counteracts the influencing of the light (5) in the first layer (1a). In this way, it is possible to realize a sensor with a high half wave voltage, so that high voltages V can be measured unambiguously. A plurality of first and second electro-optically active layers are advantageously arranged between the electrodes (3, 4).
    • 用于测量存在于两个电极(3,4)之间并产生电场E的电压V的电压传感器包括至少两层由电光活性材料制成的层(1a,2a),沿着 光路(5)。 通过这些层,通过光束,由于电光效应影响其相位和/或其极化状态。 以这样的方式选择电光活性层(1a,2a)相对于光路和电场E的取向,使得第二层(2a)中的光(5)的影响抵消影响 的第一层(1a)中的光(5)。 以这种方式,可以实现具有高半波电压的传感器,从而可以明确地测量高电压V. 多个第一和第二电光活性层有利地布置在电极(3,4)之间。
