Optically Powered Lightning Current Measurement System for High-Tower Observation
IEEE Access, 2018 The measurement of lightning striking the high tower is one of the most important ways to obtain the full-wave of lightning current. However, importance has never been attached to this important work until recent years in China. During the implementation

Verification of a novel method of detecting faults in medium-voltage systems with covered conductors [PDF]
, 2017 This paper describes the use of new methods of detecting faults in medium-voltage overhead lines built of covered conductors. The methods mainly address such faults as falling of a conductor, contacting a conductor with a tree branch, or falling a tree ...

Calibration of Rogowski Coils at High Pulsed Currents
NCSL International Workshop & Symposium Conference Proceedings 2013, 2013 Calibration of Rogowski Coils at High Pulsed Currents. The many applications of Rogowski coils include their use as current sensors in AC resistance welding. Weld quality depends on monitoring/controlling the welding currents. The accuracy of these current sensors matters, and so does the accuracy of their calibration.

Discussions on a long gap discharge to an EHV transmission tower by a rocket triggered lightning experiment [PDF]
The triggered lightning experiments using a rocket have been carried out on a winter mountain in Japan since 1986. For the four years from 1986 to 1989, 39 rockets were launched and 19 of them triggered lightning strikes.
