Myth #1. ANY SURGE PROTECTION IS BETTER THAN NO SURGE PROTECTION.

This is perhaps the most reasonable, yet the most misleading of all. With no surge protection at all, incoming surges will hit only the computer's power supply (which is considerably more surge tolerant than the data line circuitry), and will not affect the system ground level at all. Since shunt surge suppressors divert power line surges into data lines, using the wrong type of surge suppression can actually cause failures throughout the network. Thus the network is likely to be better off if individual nodes have no surge supp- ressor than if they have ones that shunt power-line surges into data-lines.

Myth #2. A UPS WILL PROVIDE DEPENDABLE SURGE PROTECTION.
Myth #3. TRANSFORMERS ARE THE BEST SURGE PROTECTORS.
Myth #4. VOLTAGE-REGULATING TRANSFORMERS ARE HELPFUL WITH COMPUTERS.
Myth #5. COMMON-MODE SURGES CAUSE COMPUTER PROBLEMS.
Myth #6. COMPUTER MODEM DAMAGE IS CAUSED BY SURGES ON THE PHONE LINE.
Myth #7. SIGNAL GROUND IS ISOLATED FROM CHASSIS GROUND.
Myth #8. THE ONLY RISK FROM THE POWER LINE IS HARDWARE DAMAGE.

    11 Myths of Surge Protection

            浪涌保护的谜题

Myth #1. ANY SURGE PROTECTION IS BETTER THAN NO SURGE PROTECTION. 谜题1. 任何浪涌保护措施都要强于没有浪涌保护的措施 This is perhaps the most reasonable, yet the most misleading of all. With no surge protection at all, incoming surges will hit only the computer's power supply (which is considerably more surge tolerant than the data line circuitry), and will not affect the system ground level at all. Since shunt surge suppressors divert power line surges into data lines, using the wrong type of surge suppression can actually cause failures throughout the network. Thus the network is likely to be better off if individual nodes have no surge supp- ressor than if they have ones that shunt power-line surges into data-lines. 这也许是最合理的，然而也是最具误导性的。在完全没有浪涌保护措施的情况下，进线的浪涌也许只是打击到电脑的供电设施（供电设施的浪涌承受能力我们认为要强于数据线的回路），完全不会影响系统地的等级。由于分流浪涌抑制器将电力线的浪涌分流到了数据线，因此使用错误型号的浪涌抑制器会在事实上导致这个网络的失败。因此如果一个节点没有浪涌抑制器，这也会强于有一个将电力线的浪涌分流到数据线的浪涌保护器。 Myth #1. ANY SURGE PROTECTION IS BETTER THAN NO SURGE PROTECTION. Myth #2. A UPS WILL PROVIDE DEPENDABLE SURGE PROTECTION.           2。一个UPS电源会提供可靠的浪涌保护 Myth #3. TRANSFORMERS ARE THE BEST SURGE PROTECTORS.           3。变压器是最好的浪涌保护装置 Myth #4. VOLTAGE-REGULATING TRANSFORMERS ARE HELPFUL WITH COMPUTERS.         4 调压变压器对保护电脑有帮助 Myth #5. COMMON-MODE SURGES CAUSE COMPUTER PROBLEMS.           5  共模浪涌造成计算机问题 Myth #6. COMPUTER MODEM DAMAGE IS CAUSED BY SURGES ON THE PHONE LINE.           6  电脑的调制解调器损坏来源于来自电话线的浪涌 Myth #7. SIGNAL GROUND IS ISOLATED FROM CHASSIS  GROUND.               信号地和保护外壳的接地时隔离的 Myth #8. THE ONLY RISK FROM THE POWER LINE IS HARDWARE DAMAGE.              来自电力线路的唯一风险是硬件的损坏 Myth #9. SURGE PROTECTORS ARE PERMANENT DEVICES.               浪涌保护器是长久（使用）的设备 Myth #10. NOTHING CAN STOP LIGHTNING.                没有什么能够阻止雷电 Myth #11. YOU GET WHAT YOU PAY FOR.                 你得到的是你支付的.....  - -！ for more info，please check：
