Radio Interference Prediction Method for EHV AC Transmission Lines at High Altitudes Based on Long‐Term Observations

High Voltage, EarlyView.
ABSTRACT Radio interference (RI) is a critical factor in the design of extra‐high voltage (EHV) transmission lines at high altitudes. To address the insufficient field data of RI on high‐altitude transmission lines, the lack of adequate validation for existing RI prediction methods, and the difficulty in assessing RI levels under various meteorological

Research on Ultra‐Wideband Pulse Current Method for DC Partial Discharge Measurement

High Voltage, EarlyView.
ABSTRACT The conventional pulse current method is commonly used in AC or DC withstand voltage tests with partial discharge (PD) monitoring. Because of its relatively narrow measurement bandwidth, this method tends to ignore critical information in PD waveforms, making it difficult to eliminate pulse‐type interference under DC voltage conditions, where ...

Ion‐Flow Field Modelling of ± 1100 kV Transmission Lines Under Strong‐Wind Scenarios Using the Multiple Relaxation Time Lattice Boltzmann Method

High Voltage, EarlyView.
ABSTRACT To solve the ion‐flow field of ultrahigh‐voltage direct current (UHVDC) transmission lines under strong‐wind scenarios, the multiple relaxation time lattice Boltzmann method (MRT‐LBM) is adopted. Compared with previous ion‐flow studies predominantly based on the single relaxation time LBM, the MRT‐LBM framework provides improved numerical ...
