High impedance faults
WebGostaríamos de lhe mostrar uma descrição aqui, mas o site que está a visitar não nos permite. WebHigh impedance faults typically occur when an energised conductor comes in contact with ground through any high impe-dance object such as dry asphalt, wet sand, dry grass and sod etc. which limits the flow of current towards ground (Jones, 1996). Timely detection of high impedance faults is neces-

Web1 de nov. de 2024 · The fault impedance is usually more than 300 Ω [5,6]. Due to the large transition impedance of the HIF, the characteristic of the fault transient signal is weak, making it difficult for fault detection. Moreover, the transient signal is easily disturbed by noise, leading to difficulty in fault location [7,8].
