切换振荡器能够检测驱动延迟、同相致动的非同时性和切换期间的弹跳。

所有特征均采用:

PKR-2配有用于周期图记录的特殊换能器。它与不同驱动器的轴的接口配有一组轴和衬套,只需戴上轴突起即可安装,无需任何工具即可安装。

所有特征均采用:

无需额外的元件(例如电阻器)或了解已检查的OLTC器件的限流电阻器的电阻即可测量参数。对特定OLTC的所有调整都在仪器中自动执行。

反应器型OLTCS可以在PKR-2设备的帮助下以静态模式进行检查。用户用标准成套的手柄以慢动作旋转驱动轴。此时,触点关闭/打开的时刻以度数以及电压和电流值显示在设备的显示屏上。

为了方便直接连接到OLTC的触点,当部分或全部排油打开油箱时,PKR-2配备了特殊的长探头。

无需接触式探头,即可使用带有鳄鱼夹的电缆连接到 OLTC。在这种情况下,应从接触器油箱进行部分或全部排油,或者应从变压器油箱中完全移除OLTC。

该仪器配备了大型传感器彩色图形显示屏,能够以图形或表格形式表示信息。高亮度和对比度使处理图形变得更加容易。

测量结果存储在仪器的非易失性存储器中,也可以传输到PC。

此外,仪器可以通过仪器键盘、传感器显示器或 个人电脑PC 进行控制。最后提到的功能允许您坐在车内使用PC记录图表,这在寒冷季节很重要且舒适。

该仪器符合GOST R 51522.1-2011对A类设备的电磁兼容性要求。

该仪器符合GOST R52319-2005对电气控制和测量仪器以及实验室设备的安全要求。
