摘要： 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.

摘要： A voltage sensor for measuring the voltage on high voltage lines is formed by an electrically isolating section of dielectric material that structures the electric field generated by a voltage difference between the two ends of the isolating section and provides screening of the electric field from other electric field sources external to the isolating section. At least one electric field sensor is provided to sense the electric field in the isolating section the output(s) of which are weighted and combined to provide an accurate measurement of the voltage between the two ends. The electric field sensors are located and their outputs are combined so that error in the voltage measurement due to the influence of external electric field sources is within an acceptable range.

摘要： Multi-phase, gas insulated electrical switchgear with optical voltage and/or current sensors are described. Compensation for contributions to sensor readings from non-associated conductors is provided. A processor is connected to voltage and/or current sensors which are placed near conductor whose voltages and/or currents are to be measured. The processor can receive outputs from those sensors and compensate the outputs for contributions which are attributable to sources other than the conductors which are intended to be measured.
