Do not operate for anything else. − Even if 100% certain that a high-impedance fault is present, give conventional protection an opportunity to operate first and sectionalize the fault, operating only if conventional protection fails.

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].
