电力专业英语(23)ElectromagneticFieldandElectromagneticCompatibility参考教材：朱永强.电力专业英语阅读与翻译.机械工业出版社，2024-06PowerQualityandItsImprovement1.Theelectromagneticenvironmentfordisturbancesoriginatinginorconductedthroughthepowersystemisequivalenttothevoltagequality.尝试翻译1.Theelectromagneticenvironmentfordisturbancesoriginatinginorconductedthroughthepowersystemisequivalenttothevoltagequality.翻译从电力系统发出的或通过电力系统传导的扰动，其电磁环境等同于电压质量。生词adj.

电磁的electromagneticn.差异，偏差deviationPowerQualityandItsImprovement说明词组isequivalentto表示“相等[当]于...,等(同)于,与...等效”。originatinginorconductedthroughthepowersystem是省略写法，补全应为：originatinginthepowersystemorconductedthroughthepowersystem。PowerQualityandItsImprovement2.Thecompatibilitylevelischosensuchthatcompatibilityisachievedformostequipmentmostofthetime:typically95%ofequipmentof95%ofthetime.尝试翻译2.Thecompatibilitylevelischosensuchthatcompatibilityisachievedformostequipmentmostofthetime:typically95%ofequipmentof95%ofthetime.生词n.

共存，和睦相处compatibility翻译兼容性水平选的是大多数设备在大部分时间里达到的兼容性：典型地取95％时间的95％的设备。PowerQualityandItsImprovement说明词组suchthat表示“如此，这样”。在这里equipment是不可数名词。PowerQualityandItsImprovement3.Herethesurgeprotectionisreferredmainlytolightningshielding,namelytodischargethepulseenergyinducedbylightingshocksinveryshorttimeinordertoprotecttheentiredevice.尝试翻译3.Herethesurgeprotectionisreferredmainlytolightningshielding,namelytodischargethepulseenergyinducedbylightingshocksinveryshorttimeinordertoprotecttheentiredevice.生词v.释放

n.放电discharge

翻译浪涌保护主要指防雷保护，就是在极短的时间内释放掉设备电流上因感应雷击而产生的大量脉冲能量到安全地线上，从而保护整个设备。n.浪涌保护，过(高峰)电压保护surgeprotection

PowerQualityandItsImprovement说明bereferredto表示“是指，指的是”。namely表示“即，也就是”PowerQualityandItsImprovement4.Fastresponseisthebasicrequirementforasuppresser;otherwise,harmwillalreadycomeforthbeforetheactionofthesuppresserifafastincreasinginstantaneouspeakvoltageappearsacrosstheprotectedcircuit.尝试翻译4.Fastresponseisthebasicrequirementforasuppresser;otherwise,harmwillalreadycomeforthbeforetheactionofthesuppresserifafastincreasinginstantaneouspeakvoltageappearsacrosstheprotectedcircuit.生词n.

抑制器suppresser翻译对抑制器的基本要求是反应速度要快，否则，如果在受保护电路的两端出现上升速度极快的瞬时峰值电压，那么在抑制器作用之前就会出现危害。n.
