    • A time division multiplexed optical voltage measuring system includes an optical voltage sensing system module including, (i) a plurality of optical sensors where each sensor is responsive to an input interrogation light wave, and (ii) one or more optical outputs affected by sensed electric field thereat. The optical voltage sensing system module includes an optical circuit arrangement having (i) an input for receiving a module specific pulsed light wave derived from a primary pulsed light wave from a remote light source, and (ii) arranged such that each of the plurality of optical sensors receives an interrogation pulsed light wave. The optical circuit arrangement of the optical voltage sensing system module further includes at least one optical wave combiner for combining like-kind of outputs from all of the plurality of optical sensors. The optical circuit is arranged such that the pulsed light waves from the outputs of different optical sensors arrive at the optical wave combiner at differing times. In turn, the output of the combiner is passed to a detector and signal processor at a remote location for signal processing, and providing a measurement of the voltage intended to be measured. In a specific embodiment, each voltage sensing modules is arranged integral with a high voltage insulator column of a multi-phase power line system.
    • 时分复用光电压测量系统包括光电压检测系统模块,该光电压检测系统模块包括:(i)多个光学传感器,其中每个传感器响应于输入询问光波,以及(ii)一个或多个受感测电 在那里 光电压检测系统模块包括光电路装置,该光电路装置具有:(i)用于接收源自远程光源的主脉冲光波的模块专用脉冲光波的输入,以及(ii)布置成使得多个 光学传感器接收询问脉冲光波。 光电压检测系统模块的光电路布置还包括至少一个光波组合器,用于组合来自所有多个光学传感器的类似类型的输出。 光路布置成使得来自不同光学传感器的输出的脉冲光波在不同时间到达光波合成器。 反过来,组合器的输出又传递到远程位置处的检测器和信号处理器进行信号处理,并提供要测量的电压的测量值。 在具体实施例中,每个电压感测模块与多相电力线系统的高压绝缘子列一体化。
