Integrated test system of generator characteristics of ARFD-2
Generator in the regular maintenance, the needs of a variety of characteristic curve of the generator and exciter were measured for comparison, to determine the maintenance results. The test method at present is: access many current meter, voltage meter, phase meter, test personnel each see a table, then a person starting, then each record their own meter readings, so there are the following risks:
(1) the test time is long, large energy consumption.
(2) generator test data, low accuracy, not timely, accurately determine the inspection results of the generator, may produce some hidden fault, fault caused by grid connected power when the generator.
(3) generator maintenance access needs a lot of testing instrument, cause many difficulties to the actual operation, and even easy to cause accident.
(4) excessive generator maintenance field personnel, prone to accidents etc..
In order to safe, accurate, effective comprehensive testing generator electrical parameters, our company in the reference of foreign advanced technology, combined with the actual situation in our country, the development of a comprehensive test system of the generator characteristics of RFD series "". The system which the notebook computer operating platform, data collector with specialization, making the generator electrical maintenance comprehensive testing more accurate, more timely, more convenient. Maintenance personnel in general simply training, can be freely to the operation of the whole test system.

发电机特性综合测试系统ARFD-2
发电机在定期检修以后,需要对发电机和励磁机的多种特性曲线进行测量比较，以判断检修结果。目前的测试手段是：接入众多的电流表、电压表、相位表，测试人员每人看一个表，再由一人发令，则每人记录自己仪表的读数，这样就存在以下隐患：
(1)测试时间长，能耗大。
(2)发电机检测数据少，准确性低，不能及时、准确地判断发电机的检修结果，有可能产生某些故障隐患，造成发电机并网发电时发生故障。
(3)发电机检修需要接入大量的测试仪表，给实际操作造成很多困难，甚至容易造成事故。
(4)发电机检修现场人员过多，容易发生意外事故等。
为了能安全、准确、有效地对发电机电气参数进行综合测试，我公司在参考国外先进技术的同时，结合我国的实际情况，开发了RFD系列"发电机特性综合测试系统"。本系统以笔记本电脑为操作平台，配以专业化的数据采集器，使得发电机电气检修综合测试变得更准确，更及时、更方便。一般的检修人员只需简单培训，就可自如地操作整个测试系统。
