Characterization and analysis of electric-field sensors

2015 IEEE Industry Applications Society Annual Meeting, 2015
With a growing number of electric-field sensors becoming commercially available, there is an increasing need for high-quality test and evaluation processes. The electric-field sensing team at US Army Research Laboratory (ARL) possesses a low-frequency electric field “cage,” which provides a ∼1-m3 volume with electric-field accuracy >99%. A state-of-the-

Development of a Wireless Sensor Network with Optical Electric Sensor for Electric Field Measurement

Wireless Personal Communications, 2017
The area of high voltage direct current (HVDC) transmission line is very large, so using cable for electric field monitoring system is very inconvenient. Wireless sensor network (WSN) can solve this problem. Compared with the traditional communication network, WSN has the advantages of small volume, high flexibility, strong self-organization.

Optical electric-field sensors

Optical Engineering, 2006
Based on the electro-optic (EO) polymer Mach–Zehnder interferometer (MZI) technology, IPITEK develops optical E-field sensor devices. As a receive antenna, the present device exhibits wide and flat bandwidth, up to 10 GHz. Testing the E-field sensor response was performed using a transverse electromagnetic (TEM) cell at frequencies from 0.2 to 1 GHz,

A sensitivity-enhanced electric field sensor with electrostatic field bias

2017 IEEE SENSORS, 2017
An electrostatic field biased cantilever electric field sensor with sensitivity improvement is proposed in this paper. Theoretically, the sensitivity of the sensor is proportional to the applied electrostatic field strength. A demonstrated sensor is developed, which consists of a Silicon cantilever coated with an Aluminum Nitride (AlN) piezoelectric ...

Lithium niobate sensor for measurement of DC electric fields

IEEE Transactions on Instrumentation and Measurement, 2001
The paper presents a theoretical analysis and experimental verification of a lithium niobate electrooptic sensor for measurement of DC electric fields in a space charge environment. Both unipolar and bipolar charge environments were investigated. In both cases the sensor output is linearly dependent on the measured electric field and independent of the
