The lifespan assessment and maintenance planning of high-voltage power systems requires
condition monitoring of all the operational equipment in a specific area. Electrical insulation …

Partial Discharge (PD) activity is a pre-cursor for insulation degradation which may
eventually lead to catastrophic failure of the electrical equipment with severe social and …

This paper presents the finite element method (FEM) simulation of the propagation,
measurement and evaluation of the time of arrival (TOA) of the acoustic wave created by a …

This study proposes a stepwise accuracy enhancement (SAE) method for jointly estimating
signal propagation speed, near-field position, and far-field direction-of-arrival (DOA) without …

Received signal strength (RSS) based localization of a source is a simple but effective
technique. In RSS based localization source location is estimated by converting obtained …

Covered conductors represent an alternative to classic ACSR for overhead high-voltage
distribution lines. They were first put into operation in the 1970s, especially in the USA and …

Partial Discharge (PD) is an initial phenomenon of a breakdown of isolation equipment. The
continuous failure will damage power equipment lead to a breakdown. Early detection of PD …

Partial Discharge (PD) is an electrical discharge that occurs within part of the dielectric
between two High Voltage (HV) conductors. PD causes damage to the dielectric which …

Partial Discharge (PD) detection plays a vital role in electrical power stations, it can help
protecting the high voltage equipment, it can prevent explosion of these equipment and …

O processo de medição de descargas parciais tem uma longa história como ferramenta de
avaliação de envelhecimento de equipamentos de alta tensão. A localização, porém, ainda …
