设置仪器是使用仪器前面板键盘输入矢量组并连接到离线变压器的简单案例。
通过在每次测量之前自动执行的初级和次级电压端子处的连接和短路过程连续测量所有三个相。如果需要,也可以仅测量一个相。
可调整的设定值允许显示任何误差或偏离所需的变比。4167F也可以控制变压器分接开关,在这种情况下,所有的相位和分接头都是连续测量的。结果可以使用变压器专用存储卡在内部存储,打印到外部打印机或通过RS232接口传输到PC。
通过使用为特定变压器类型预编程的存储卡,可以使仪器显示具有实际读数的PASS / FAIL消息。
变压器专用存储卡可以通过使用内置读卡器的个人计算机或直接连接到个人计算机的成本有效的外部读卡器/写卡器轻松编程。
功能是自动矢量组检测。如果已完成与变压器的所有连接,则将检测到正确的矢量组。在缺少连接(例如1N或2N)的情况下,将向用户显示最多三个可能的向量组。一旦选择了正确的矢量组,仪器将学习这一组,下一次将首先展示该组。
4167F通过四个连接分别连接到HV和LV绕组。它还以内部隔离变压器提供的预设电压为变压器供电。然而,使用不同电压和频率的外部激励也是可能的。设置简单。
4167F采用坚固的手提箱。所有连接均在仪器的前面板上提供并锁定,以避免在测量过程中意外断开。还可以使用报警警告灯,并在测量过程中点亮。
Setting up the instrument is a simple case of typing in the vector group using the instrument front panel keypad and connecting to the offline transformer. All three phases are measured consecutively
with connecting and short circuit procedures at the primary and secondary voltage terminals performed automatically before each measurement. It is also possible to measure just one phase if required.
An adjustable set value permits the display of any error or deviation from the required transformation ratio. It is also possible for the 4167F to control the transformer tap changer and in this case all phases and taps are measured consecutively. Results can be stored internally using a transformer specific memory card, printed to an external printer or transferred to a PC via an RS232 interface.
By using a memory card, pre-programmed for a specific transformer type, the instrument can be made to show a PASS / FAIL message with the actual reading.
The transformer specific memory cards can be easily programmed via a personal computer using the built in card reader or by a cost efficient external card reader/writer directly connecting to a personal computer.
A market unique feature is the automatic vector group detection. If all connections to the transformer have been made, the correct vector group will be detected. In case of missing a connection (1N or 2N e.g.) there will be up to three possible vector groups displayed to the user. Once the correct vector group has been selected the instruments learns this and that group will be presented first next time.
The 4167F is connected to the H.V. and L.V. windings via four connections each. It also powers the transformer at a preset voltage supplied by an internal isolating transformer. However, external excitation using different voltages and frequencies is also possible. is its simplicity to set-up.
The 4167F is housed in a robust carrying case. All connections are provided at the front panel of the instrument and are locked in order to avoid accidental disconnection during a measurement. An alarm-warning lamp is also available and will illuminate whilst a measurement is in progress.
