产品详细资料
由于自动配置，绕组中的电流可能会发生相移，或者可能会去除零序分量（请参阅第5-6页的自动配置）。作为计算输入电流与差动电流关系的替代方案，差动电流显示在A2 METERING中 电流，电流 有差别的。当元件工作时，确保显示的值与小拾取设置相同。 检查跳闸和信息LED是否闪烁，并显示以下跳闸信息之一：LATCHED a:Percent Differential，或OPERATED a:Percent-DifferentialNote上述信息将根据S4 ELEMENTS指示OPERATED或LATCHED 有差别的 差分百分比 百分比差异目标设置。要独立验证自动配置是否导致电流与测量值一致，请遵循以下步骤中概述的规则。 在第5-13页的表5-1:变压器类型中查找变压器类型。 对于特定矢量集的相移，从第5-24页的表5-2:相移中确定应用于该绕组的电流矢量的处理。 使用第5-24页表5-2:相移中的公式计算“虚线”电流值。如果适用，请使用零序去除计算。这适用于所有三角形绕组和Y形-Y形变压器的两个绕组。计算处理后的电流矢量，以获得该绕组的“虚线”值。
The currents in the winding may be phase shifted or may have the zero-sequence component removed due to auto-configuration (see Auto-configuration on page 5–6). As an alternate to calculating to relation of input current to differential current, the differential current is displayed in A2 METERING  CURRENT  DIFFERENTIAL. Ensure that the displayed value is the same as the minimum pickup setting when the element operates.  Check that the Trip and Message LEDs are flashing and one of the following trip messages is displayed: LATCHED a: Percent Differential, or OPERATED a: Percent Differential Note The above messages will indicate either OPERATED or LATCHED depending on the S4 ELEMENTS  DIFFERENTIAL  PERCENT DIFFERENTIAL  PERCENT DIFFERENTIAL TARGET setting. To independently verify that auto-configuration causes the currents to be as measured, follow the rules outlined in the steps below.  Look up transformer type in Table 5–1: Transformer types on page 5– 13. For the phase shift for the particular set of vectors, determine the processing applied to the current vectors for that winding from Table 5– 2: Phase shifts on page 5–24.  Calculate the “dashed” current values using the equations in Table 5–2: Phase shifts on page 5–24. If applicable, use the zero-sequence removal computation. This is applicable for all Delta windings and for both windings of a wye-wye transformer. Compute the processed current vectors to obtain the “dashed” values for that winding.
