Explanation of Terms术语的解释:
Overvoltages or surge voltages:
Overvoltage is the permanent or temporary voltagebetween conducters or between conductor and groundin systems which can damaging (electrical) equipment
过电压是在系统中的导线之间或在导线和地之间的常态的或
暂态的电压,这种电压是能损坏(电子) 仪器的。
过电压或浪涌电压
Explanation of Terms术语的解释:
暂态过电压(TOV):高压系统接地故障出现的过电压。
持续时间 ms 数量级。
permanent 常态过电压/过电流:工频(50HZ)或直流
Surge瞬态电涌: 斜三角波
持续时间μs、ns 数量级。
