Abstract: An optical voltage sensor assembly includes an input fiber-optic collimator positioned and configured to collimate input light beam from a light source. A crystal material is positioned to receive the input light beam from the light source and configured to exhibit the Pockels effect when an electric field is applied through the crystal material. An output fiber-optic collimator is positioned to receive an output light beam from the crystal material and configured to focus the output light beam from the crystal onto a detector. Methods of using the optical voltage sensor assembly are also disclosed.

Abstract: One aspect of the present technology relates to a safety cable vibration monitoring system. The system includes a vibration sensor configured to be coupled to a safety cable. A vibration monitoring computing device is coupled to the vibration sensor. The vibration monitoring computing device includes a processor and a memory coupled to the processor which is configured to execute one or more programmed instructions comprising and stored in the memory to receive data from the vibration sensor. An occurrence of a fall event related to use of the safety cable is determined based on the received data from the vibration sensor. A method of monitoring a safety cable and a safety cable monitoring network are also disclosed.

Abstract: One aspect of the present technology relates to an optical electric field sensor device. The device includes a non-conductive housing configured to be located proximate to an electric field. A voltage sensor assembly is positioned within the housing and includes a crystal material positioned to receive an input light beam from a first light source through a first optical fiber. The crystal material is configured to exhibit a Pockels effect when an electric field is applied when the housing is located proximate to the electric field to provide an output light beam to a detector through a second optical fiber. An optical cable is coupled to the housing and configured to house at least a portion of the first optical fiber and the second optical fiber. The first light source and the detector are located remotely from the housing. A method of detecting an electric field is also disclosed.
