射频监测仪说明书
射频监测仪装置原理：发电机内部的放电现象在定子绕组中产生很多的高频分量，电弧发电辐射的电磁波频谱很广，其中一部分将传入定子绕组的中性点接地线中，由于发电机中性点对地电位很低，发电机任何部位的电弧放电都将在中性点接地线内产生相应的射频电流，射频监测仪是通过高频电流传感器来监测发电机中性点的电弧的高频信号，以发现定子线圈内部放电现象。
由于发电机定子线圈中存在多种射频干扰信号，其发放电流信号通过中性点接地线流向接地点，高频电流互感器把此射频信号耦合到监测仪，该射频检测仪可以监测到放电电流的强弱，以此来探测发电机局部放电的程度，实现对发电机定子绝缘的状态检测及故障报警。
运行监视1．装置构成①监测仪、遥控板、高频电流传感器、熔丝及涌浪电容注：监测仪和遥控板的操作面板功能基本相同，监测仪显示是指针显示，还有两个多圈电位器（设置报警值，因为带锁，调整前先松锁，完毕后锁紧）而遥控板是液晶表屏显示，无法设置报警值。
②本装置监测仪引自杂用MMC A段02D柜遥控板电源引自集控楼PC＆MCC A 段07A 柜（杂用MCC A段02E柜为其备用电源）③熔丝及涌浪电容的功用高频电流传感器接在发电机中性接地变压器前面，由于高阻变压器对射频信号衰减很大，使监测仪的读数无法读出，因此设置一个涌浪电容器（0.01uf，DC 100KV），并联在接地变上，同时为了不因电容漏电引起误电流，在电容器支路上串接一限流容丝(0.5-1A / 10-27V)。
2．指示灯注：上述四个指示灯并带按键功能，即可分别进行电源开关，自校检测，报警复位操作3．装置自检周期为60S，按下遥控板或监测仪上自校按扭，仪器进入自校周期。
在前半个周期读出输出值应小于30uv,后半个周期输出接近满刻度10Kuv，10S后开始进入报警状态。
在自校周期结束后，按下各报警验证按钮，仪器进入监测状态。
4．遥控板与监测仪接通通过监测仪电源供应部件板上开关S1控制，S1拨到“OFF/REMOTE”接通，而S1拨到“ON/SELF”不接通5．报警处理验证报警并观察指示记录，以确定报警信号继续存在，关注发电机运行参数以及其他监测仪的情况，进行综合分析，并与厂家联系。

8717系列电磁射频测量仪说明书
P/N 43004100 Rev.A1981FirmwareThe Series 8717-117XX and the Model 8718B use identical firmware (internal software) and identical User’s Software. There is only one minor difference in the operation that involves the default setting for the LCD backlight:The default setting for the LCD backlight is ON for theline operated Series 8717-117XX and it is OFF for thehand-held Model 8718B.The firmware in both meters can be used to turn the backlight on and off.Controls and IndicatorsPower Control:It is suggested that the keypad be used to turn the Series 8717 on and off under normal conditions. Shut the meter off using the keypad prior to moving the ACON/OFF on the rear of the meter to the OFF position.The LINE POWER indicator on the front panel is designed to moni-tor the status of the AC power Switch.Alarm:The nine-pin alarm connector on the rear panel pro-vides a simple way for remote indication that the user-controlled alarm threshold has been exceeded. Both a TTL signal and a set of SPDT relay contacts are provided to indicate alarm sta-tus. The meter firmware is used to turn the alarm on and off and to set the alarm threshold. The alarm threshold is set in proportion to the full-scale value of the probe that is being used. For example, if a shaped probe with a full scale indication of “300% of Standard” is used and the alarm threshold is set to 10%, then the audio alarm on the front panel will be activated whenever the probe is subjected to a field in excess of 30% of Standard. The TTL signal and the relay contacts operate in par-allel to the front panel audio signal. The TTL signal goes High under alarm conditions.Interface Switch:The interface switch activates one of the two remote interfaces – the GPIB or the RS232serial port. Although the GPIB interface is most likely to be used for day-to-day oper-ation, the RS232 interface is required to run Narda ’s User ’s Software, which is designed to operate via the RS232 port only.Therefore, you must select RS232 in order to load probe cali-bration information or to extract logged data. It is convenient to have probe calibration information stored in the meter when making single-frequency measurements. Under those condi-tions, probe correction factors can be used to reduce theamount of measurement uncertainty. Refer to the 8718B User’s Guide for further information.Other:For all other operations refer to the 8718B User ’s Guide.USA: 435 Moreland RoadHauppauge, NY 11788Tel 1-631 231-1700 Fax 1-631 231-1711E-Mail *******************www GERMANY: Sandwiesenstr 7D-72793 PfullingenTel +49-7121-9732-777 Fax +49-7121-9732-790E-Mail ********************www.narda-sts.de ❖❖❖CAUTION ❖❖❖Do not place your eye tightly against the front panel of the meter in the area of the Probe Test window while the Test Source indicator is illuminated.Probe Test:The output of the high frequency test source is very low power.

大型汽轮发电机和大型高压交流电动机中，由于定子绕组的故障（如绝缘磨损、接线开焊、股线断裂、高电场造成电晕等）会导致发电机运行中内部放电量增加，严重时，放电处将产生弧光，会导致局部过热和损坏绕组对地绝缘，严重影响发电机的绝缘寿命。
发电机内部的放电现象必然在定子绕组中产生很多高频分量，电弧放电辐射的电磁波频谱很广，其中一部分将传入定子绕组的中性点接地线中。
由于发电机中性点对地电位很低，发电机内任何部位的电弧放电都将会在中性点接地线内产生相应的射频电流，射频监测仪是通过高频电流传感器来监测发电机中性点上的电弧的高频信号，以发现定子线圈内部放电现象。
由于发电机定子绕组中存在着多种射频干扰信号，其发放电电流信号通过中性点接地线流向接地点，高频电流互感器把此射频信号耦合到监测仪，该射频监测仪可以监测到放电电流的强弱，以此来探测发电机局部放电的程度，实现对发电机定子绝缘的状态监测及故障报警。

RF Explorer MS2711B D 手持射频分析仪说明书
The MS2711B/D Handheld Spectrum Analyzer provides the “ulti-mate” in measurement flexibility for field environments and applica-tions requiring mobility. Unlike traditional spectrum analyzers, the MS2711B/D features a rugged, ultra-lightweight, battery-operated design that enables users to conduct spectrum analysis measure-ments – anywhere, anytime.Providing complete freedom from AC/DC power requirements, the MS2711B/D enables you to locate, identify, record and solve com-munication systems problems quickly and easily, without sacrificing measurement accuracy.Whether you are installing, maintaining, or troubleshooting a modern wireless communication system, the MS2711B/D provides excep-tional performance combined with ease-of-use and broad functional-ity – making it an ideal solution for engineers and technicians who conduct field measurements in the 100 kHz to 3.0 GHz frequency range. In fact, it is ideal for finding the source of interfering signals in modern wireless systems.Rugged and ReliableBecause the MS2711B/D was designed specifically for field environ-ments, it can easily withstand the day-to-day punishment of field use. Rugged packaging also keeps the MS2711B/D performing in harsh environments.Easy-to-UseNot only is the MS2711B/D the lightest fully-functional spectrum an-alyzer available at 4.5 pounds (base model including battery), oper-ation is straight-forward and driven by firmware that simplifies the process of making measurements and interpreting the results shown on the large, high-resolution LCD display. The menu-driven user in-terface is easy to use and requires little training.A full range of marker capabilities such as peak, center and delta functions are also provided, giving users a faster and more compre-hensive measurement of displayed signals. Limit lines simplify am-plitude measurements, giving users the capability to create quick, simple, pass/fail measurements. Frequency, span and amplitude functions are easily configured for optimum performance. Used to-gether with the Save Setup feature, these functions can help to make testing easier and faster for less experienced users.Powerful Trace ManagementUsers are able to store ten test setups along with 200 measurement traces internally in the unit’s memory. The stored data can be easily down-loaded to a personal computer (PC) or a printer via an RS-232 serial cable for further analysis. A notebook computer can be used with the RS-232 interface for automated control and data collection in the field.A standard preamplifier (option 8) plus a number of available options including an internal tracking generator (option 20, MS2711B) or transmission measurement (option 21, MS2711D) expand the MS2711B/D’s capabilities.Fast, Accurate, Repeatable,Portable Spectrum AnalysisTo meet the challenges of today’s wireless market, Anritsu Companyhas incorporated a pre-amp (standard) for its revolutionaryMS2711B/D Handheld Spectrum Analyzer which increases the ana-lyzer’s sensitivity and dynamic range while improving measurementtime. With the built-in pre-amp feature, the MS2711B/D is particular-ly effective in measuring low-level signals. The handheld spectrumanalyzer’s sensitivity is improved to –115 dBm for MS2711B and–135 dBm for MS2711D (100 Hz RBW) (full span). With this option,the MS2711B/D can identify and make measurements on low-levelsignals much faster than previously possible.The improved sensitivity, dynamic range, and measurement speedcomplement the existing benefits of the MS2711B/D. Weighing only4.9 pounds (including a NiMH battery, fully loaded, base model only4.5 pounds), the MS2711B/D is the world’s lightest fully functionalhandheld spectrum analyzer with the built-in tracking generator op-tion (option 20).MS2711B/D has been enhanced so that it can make highly accuratechannel power measurements, occupied bandwidth and AdjacentChannel Power Ratio (ACPR) measurements. These are increasing-ly critical measurements, particularly for power amplifiers used inwireless communication systems. With the enhancements, theMS2711B/D has dedicated one button channel power, occupiedbandwidth, and ACPR measurement capability to significantly re-duce test time and expense. The MS2711B/D also features local lan-guage graphical user interface support (in Chinese, Japanese,French, German, and Spanish).N E W316For product ordering information, see pages 3 – 6 3175Features•Lightweight (4.5 lbs - base model, 4.9 lbs with tracking generator -option 20, or transmission measurement, option 21) •Synthesizer-based performance •Wide dynamic range•One button, ACPR, OBW, channel power, C/I measurement •Quick zoom-in, zoom-out display •5 minute warm up•Manual and automatic attenuator control•Improved user interface, with local language support in five differ-ent languages•Automatic overload and ESD protection •Built-in AM/FM demodulation•Built-in field strength measurement •Built-in interference analysis•Ability to store and recall up to six antenna factors•Full range of marker capabilities including peak, center, and delta functions•Limit lines for quick, simple pass/fail measurements •Rugged, reliable packaging •Battery operated design–2.5 hours of continuous operation–Built-in energy conservation that extends battery life beyond an eight-hour workday–Operation using a 12.5 Vdc source AC-DC adapter or automotive cigarette lighter adapter, which simultaneously charges the battery –Field replaceable battery •Built in clock and calender•Low cost ownership, global warranty•Data storage and memory–Store up to ten test setups and 200 measurement traces in non-volatile memory–Stored data is easily and quickly downloaded to a personal com-puter (PC) or printer•Powerful trace management–Automatically date/time stamped –Alphanumeric labeling •PC reporting software–Windows ®95/98/2000/ME, XP , NT Workstation compatible –Supports long file names for descriptive labeling–Can display an unlimited number of traces for comparison to his-torical performance•Optional Monochrome or Color LCD with backlight capability display •Direct printer control via RS232 serial portApplicationsConvenient operating procedures, high sensitivity, and excellent re-peatability enable the MS2711B/D to pinpoint the smallest system performance degradation and allow for easy verification of system compliance.

射频监测仪
装置原理：
发电机内部的放电现象在定子绕组中产生很多的高频分量，电弧发电辐射的电磁波频谱很广，其中一部分将传入定子绕组的中性点接地线中，由于发电机中性点对地电位很低，发电机任何部位的电弧放电都将在中性点接地线内产生相应的射频电流，射频监测仪是通过高频电流传感器来监测发电机中性点的电弧的高频信号，以发现定子线圈内部放电现象。
由于发电机定子线圈中存在多种射频干扰信号，其发放电流信号通过中性点接地线流向接地点，高频电流互感器把此射频信号耦合到监测仪，该射频检测仪可以监测到放电电流的强弱，以此来探测发电机局部放电的程度，实现对发电机定子绝缘的状态检测及故障报警。
运行监视
1．装置构成
①监测仪、遥控板、高频电流传感器、熔丝及涌浪电容
注：监测仪和遥控板的操作面板功能基本相同，监测仪显示是指针显示，还有两个多圈电位器（设置报警值，因为带锁，调整前先松锁，完毕后锁紧）而遥控板是液晶表屏显示，无法设置报警值。
②本装置监测仪引自杂用MMC A段02D柜
遥控板电源引自集控楼PC＆MCC A 段07A 柜（杂用MCC A段02E柜为其备用电源）
③熔丝及涌浪电容的功用
高频电流传感器接在发电机中性接地变压器前面，由于高阻变压器对射频信号衰减很大，使监测仪的读数无法读出，因此设置一个涌浪电容器（0.01uf，DC 100KV），并联在接地变上，同时为了不因电容漏电引起误电流，在电容器支路上串接一限流容丝
(0.5-1A / 10-27V)。
2．指示灯
注：上述四个指示灯并带按键功能，即可分别进行电源开关，自校检测，报警复位操作
3．装置自检周期为60S，按下遥控板或监测仪上自校按扭，仪器进入自校周期。
在前半个周期读出输出值应小于30uv,后半个周期输出接近满刻度10Kuv，10S后开始进入报警状态。
在自校周期结束后，按下各报警验证按钮，仪器进入监测状态。
4．遥控板与监测仪接通通过监测仪电源供应部件板上开关S1控制，S1拨到“OFF/REMOTE”接通，而S1拨到“ON/SELF”不接通
5．报警处理
验证报警并观察指示记录，以确定报警信号继续存在，关注发电机运行参数以及其他监测仪的情况，进行综合分析，并与厂家联系。
