Overvoltage protection: When the fault voltage exceeds the protection setting value, a trip command or overvoltage signal is issued.
Low-voltage protection: When the fault voltage is lower than the protection setting value, a trip command or low-voltage signal is issued.
Overvoltage protection
Overvoltage refers to any voltage whose peak value is greater than the corresponding peak value of the maximum steady state voltage under normal operation. In engineering, it refers to any dangerous voltage that may cause damage to the equipment. Therefore, in the project, some overvoltages that are larger than the normal operating voltage but are not enough to endanger the normal operation of the equipment are excluded. Overvoltage includes:
(1) Transient overvoltage, duration of milliseconds or less, is the main protection target for lightning arresters.
(2) Transient overvoltage or short-term overvoltage, the duration is relatively long, generally between 0.1s and 1s.
The sources of transient overvoltages are: lightning strikes, switching operations, electrostatic discharges, and nuclear explosions. At the communications station, lightning overvoltages or lightning overvoltages are predominant.
Transient overvoltages mainly include: over-voltage transfer, zero-off over-voltage, over-voltage resonance over-voltage and over-voltage caused by the drift of the neutral line. In addition, capacitive effects, unbalanced ground faults, and sudden load dumps on no-load lines can also create dangerous overvoltages.
