Abstract
Apparatus for measuring a high voltage electric field, such as may be used in simulating lightning strikes or the like on a test specimen, is disclosed. In general, a capacitive electric field sensor is disclosed which utilizes a pair of spaced conductors or electrodes and which is placed in the field to be measured. The conductors shield a device within the sensor which generates a signal responsive to the intensity of the electric field. This signal is transmitted to a remote data acquisition system by means of non-electrically conductive data transmission lines (e.g., fiber optic transmission lines) so as to electrically isolate the sensor and the data acquisition system whereby the sensor only minimally distorts or affects the field being measured thereby. A method for measuring high voltage electric fields is also disclosed.
