High Voltage, Volume 11, Issue 1, Page 192-200, February 2026.ABSTRACT Surface discharge is a typical fault type in electric power equipment. High temperature in long‐term operation can easily lead to ageing of materials, resulting in changes in surface characteristics and surface discharge faults. In this paper, a method of surface discharge identification of silicon rubber (SiR) based on spectral detection ...

Power Line Communication as a Sensor: Medium Voltage Cable Diagnostics
IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.This article investigates the use of broadband power line (BPL) communication as a diagnostic tool for medium‐voltage cables. Experimental results show that BPL modem parameters change in the presence of partial discharges, enabling real‐time monitoring of insulation health and supporting predictive maintenance.

IET Science, Measurement &Technology, Volume 20, Issue 1, January/December 2026.A series resistive‐capacitive divider for harmonic voltage measurement of gas‐insulated switchgear was studied. It can step down the voltage while amplifying the proportion of harmonics in the total sensed voltage, thereby increasing the significant figure for the measurement and enabling the accurate measurement of high‐order, low‐amplitude harmonics.
