An electrical field detector includes an electromechanical oscillator, part of which is included of a piezoelectric element, a frequency measuring device which is coupled to the oscillator so as to measure the oscillation frequency, and an electrical masking assembly. The electrical masking assembly is arranged close to the piezoelectric element so that, during an use of the detector, the piezoelectric element moves by vibrating relative to the electrical masking assembly. A variable part of the piezoelectric element is thus exposed to the electrical field to be measured. A change in the oscillating frequency then forms an electrical field measurement result.

Examples include a structure adapted for monitoring electric charge characteristics of the structure, where the wind turbine generator includes an electric charge monitoring system including one or more electrostatic sensors adapted for measuring polarity, the one or more electrostatic sensors being configured for measuring an electrostatic potential of one or more parts or at locations of the structure, where sensory data from the electrostatic sensors are time-stamped and time-synchronised, and the electric charge monitoring system is configured for monitoring charge characteristics at the one or more parts or locations of the structure.

An interferometric radioimager provides real-time, high-fidelity radioimaging of high voltage breakdown (HVB) both internal and external to electrical components at sub-nanosecond and sub-millimeter resolution and has an ability to resolve multiple/spatially-extensive HVB simultaneously. Therefore, radioimaging can be used to screen for early life weakness/failure and enable non-destructive screening of defective electrical components. In particular, radioimaging can detect precursors to catastrophic HVB, allowing for early detection of weakness in critical electrical components. Radioimaging can also be used to track HVB and pinpoint defects in electrical components real time, including transformers, capacitors, cables, switches, and microelectronics.

A sensor assembly includes a connecting bar extending along a longitudinal axis and a tubular body extending along the longitudinal axis and at least partially surrounding the connecting bar such that the tubular body is radially spaced from the connecting bar. The tubular body includes a support member made of insulating material. The tubular body also includes a first section with an electric field sensor comprising a first layer of electrically conductive material on an inner surface of the support member to detect an electric field produced by the connecting bar. The first section also includes a first electric screen comprising a second layer of electrically conductive material on an outer surface of the support member to shield the electric field sensor from outside electrical interference. A second section disposed adjacent the first section includes a second electric screen. A dielectric material at least partially encloses the tubular body.
