additional phase error
相关语句
  附加相位差
     EFFECT OF CVT ADDITIONAL PHASE ERROR ON INSULATION MONITORING ON SITE
     电容式电压互感器附加相位差对绝缘在线监测的影响
短句来源
     Normally,a reference voltage is obtained from the secondary side of potential transformer for insulation monitoring system on site. However,when the reference voltage is from a capacitive voltage transformer(CVT),additional phase error will appear,which has considerable effects on the monitoring results.
     绝缘在线监测系统一般从电压互感器二次侧取参考电压信号,当采用电容式电压互感器(CVT)二次侧电压作为测量基准时,其附加相位差对监测结果的准确度有不可忽略的影响。

A novel configuration for millimeter-wave(mm-wave) radio-over-fiber transmission systems with remote local-oscillator(LO) delivery was proposed.The proposed technique provides a very simple solution to base-station access points for pico-cellular networks in order to distribute the future broadband wireless-access services.Both numerical and simulation results show that,622 Mbit/s binaryphase-shift-keying(BPSK) data in the downlink can be successfully transmitted with a bit error rate ≤10~-9 over 30 km of a conventional single-mode fiber,for a laser output power of-6.5 dBm,an optical gain of 6 dB,and laser linewidths(LLW′s) of 1 MHz,75 MHz,and 150 MHz,respectively.The variance of an additional phase error of the remotely delivered mm-wave LO due to laser phase noise and fiber dispersion is calculated to be only about 30.4 mrad(1.74°),in the case of the relatively large LLW of 150 MHz and a fiber length of 30 km.
