WebOne voltage measurement method is to measure voltage with respect to a common, or a “ground,” point. Oftentimes, these “grounds” are stable and unchanging and are most commonly around 0 V. Historically, the term ground originated from the usual application of ensuring the voltage potential is at 0 V by connecting the signal directly to ... Web15. Earthing of voltage surge protectors. This is designed to discharge the fault currents resulting from the elimination of overvoltages. These conductors must be as short as …
WebSep 21, 2024 · As a result, earth fault detection relays will monitor the phase-earth voltage on each line. (This will create a very weak star (wye) point on the system.) When an earth fault is detected on one phase then that phase is deliberately shorted to earth. This can help make fallen wires less likely to electrocute someone.
