Adjustable Delay Time DC Voltage Monitoring Relay For Overvoltage And Undervoltage

(1) Transient overvoltage, with a duration of milliseconds or less, is the main protection object of the arrester.
(2) Transient overvoltage or short-time overvoltage, the duration is relatively long, generally between 0.1s and 1s.
Sources of transient overvoltages are: lightning strikes, switching operations, electrostatic discharges, and nuclear explosions. At the communication station, it is mainly lightning overvoltage or lightning overvoltage.
Transient overvoltages are mainly: overvoltages caused by over-voltage, zero-crossing overvoltage, disconnected resonant overvoltage, and neutral drift. In addition, capacitive effects of no-load lines, asymmetrical ground faults, and sudden load dumps can also create dangerous overvoltages.
