Corona Detection System on Insulators via Acoustic Emissions

This paper presents a computational package and equipment with the purpose to detect corona problems of insulators in transmission lines. Low-cost equipment detects presence of corona, via acoustic emissions and stores them in a memory. These data are processed by computer programs. The applicability of this equipment is immediate for any transmission company, because the perfect understanding of the operational capacity of its lines in various operating conditions and climate change allows for a safer operation with improvement of quality of service provided.
