功能介绍
按-g/t 20847.7电子式电压互感器及g/t 20847.8电子式电流互感器的规定,电子式互感器(ect/evt)有模拟量输出和数字量输出两种。本校验系统按照-g/t 20847.7/8电子式互感器标准和iec61850通讯标准,基于虚拟仪器,可实现电子式互感器模拟和数字量输出的比差、相差的测量,记录,及电子式互感器的在线测量比对。为广大电力试验、计量、施工单位提供一种可移动的电子式互感器校验装置。
该校验系统既可以完成电子式电流互感器的校验也可以完成电子式电压互感器的校验。该系统分为电流标准通道,电压标准通道,电流被测通道,电压被测通道,校验仪数据处理平台。电流标准通道由升流器、标准电流互感器、标准转换器组成。电流被测通道由升流器、被校互感器组成。校验仪通过采集器获取标准电流传感器和被校电流传感器的电参量,并将这些电参量以标准格式上传给计算机,计算机数据处理平台将同一时刻的两个信号进行比对处理,计算出被校电流传感器的误差情况,显示并记录测量结果。电压标准通道由升压器、标准电压互感器、标准转换器组成。电压被测通道由升压器、被校互感器组成。工作原理与电流校验系统相同。

main features
according to the national standard g / t 20847.7 electronic voltage transformer&g / t 20847.8 electronic current transformer requirements, electronic transformer (ect / evt) has two kinds of -og output&digital output. the calibration system is based on the virtual instrument, which can realize the measurement of difference, difference between -og&digital output of the electronic transformer, according to gb / t20847.7 / 8 electronic transformer standard&iec61850 communication standard. on - line measurement comparison of transformer. for the majority of power testing, measurement, construction units to provide a removable electronic transformer calibration device.
the calibration system can complete the electronic current transformer calibration can also complete the electronic voltage transformer calibration. the system is divided into current standard channel, the voltage standard channel, the current measured channel, the voltage measured channel, calibrator data processing platform. the current standard channel consists of a booster, a standard current transformer,&a standard converter. current measured by the current channel channel, the school was composed of transformers. the calibrator obtains the electric parameters of the standard current sensor&the calibrated current sensor through the collector,&uploads these electrical parameters to the computer in the standard format. the computer data processing platform compares the two signals at the same time, the school current sensor error situation, display&record the measurement results. voltage standard channel from the booster, the standard voltage transformer, the standard converter components. voltage measured by the booster channel, the school was composed of transformers. the operating principle is the same as the current calibration system.
