Real-Time Polarimetric Optical High-Voltage Sensor Using Phase-Controlled Demodulation
(Ieee-inst Electrical Electronics Engineers Inc, 2018-08-15)
Modern smart grid designs demand reliable sensors throughout the power delivery systems, not only to monitor the quality of the electrical energy generated by different technologies (wind, solar, hydroelectric, thermoelectric, ...
Polarimetric Optical High-Voltage Sensor Using Synthetic-Heterodyne Demodulation and Hilbert Transform With Gain Control Feedback
(Ieee-inst Electrical Electronics Engineers Inc, 2017-03-01)
Optical voltage sensors are widely used for high-voltage (HV) sensing, but the measurement accuracy is often compromised by a sensitivity drift due to variations in the ambient conditions. Synthetic-heterodyne demodulation ...
