五次谐波抑制验证五次谐波限制的操作需要能够产生包含基波和五次谐波的电流信号的测试设备。大多数现代专用继电器测试仪器，如Powertec（或Manta）的DFR、Doble或MultiAmp仪器，都能够产生适当的信号。具有适当额定输出的功率运算放大器或功率音频放大器也可以用于产生适当的信号。 按照以下方式连接测试装置，以提供A相元件。将基本电流水平设置为CT额定二次值。应操作A相的谐波抑制差动元件。 将5次谐波分量增加到远高于S4 ELEMENTS的值 有差别的 第5次HARM抑制 第5次谐波抑制电平设置。 移除总电流信号并重新施加。继电器不应工作。 减小5次谐波分量，直到元件工作。 根据以下公式计算要抑制的5次谐波百分比：将该值与继电器设置进行比较。7.5.2.11通电检测方案——关于该功能的描述，请参阅第5-48页的差动元件。此功能多可由三个输入激活：断路器辅助开关、低于阈值的电流或无电压。以下步骤测试当前级别启用功能。类似的方法可以使用适当的测试设备验证其他两种启用功能。 通过设置S4 ELEMENTS启用通电检测方案 有差别的 通电抑制 ENERGIZATION INHIBIT FUNCTION（通电抑制功能）变为Enabled（启用）。 在S4 ELEMENTS（S4元件）中进行以下设定点更改 有差别的 通电抑制设定点菜单：通电抑制参数：“2nd”谐波平均值：“Disabled”通电抑制水平：“15%”通电禁止持续时间：“5s”通电电流感应：“Enabled”通电阻止/小通电电流：“0.10×CT” 预设电流，谐波含量刚好高于“通电期间”使用的通电抑制电平。
Fifth Harmonic Restraint Verifying the operation of the 5th harmonic restraint requires test equipment capable of generating a current signal containing a fundamental and 5th harmonic. Most modern dedicated relay test instruments, such as Powertec's (or Manta) DFR, Doble, or MultiAmp instruments are capable of generating appropriate signals. A power operational amplifier with a suitably rated output, or a power audio amplifier, may also be used to generate the appropriate signal.  Connect the test setup as below to supply the phase A element. Set the fundamental current level to the CT rated secondary value. The harmonic restraint differential element of phase A should be operated. Increase the 5th harmonic component to a value well above the S4 ELEMENTS  DIFFERENTIAL  5th HARM INHIBIT  5th HARMONIC INHIBIT LEVEL setting.  Remove the total current signal and reapply. The relay should not operate.  Decrease the 5th harmonic component until the element operates.  Calculate the percentage 5th harmonic to restrain from the following equation:Compare this value to the relay setting. 7.5.2.11 Energization Detection Scheme Refer to Differential Element on page 5–48 for a description of this feature. This feature is activated by up to three inputs: breaker auxiliary switch, current below a threshold, or absence of voltage. The procedure below tests the current-level enabling feature. A similar approach can verify the other two enabling functions with the proper test equipment.  Enable the Energization Detection Scheme by setting S4 ELEMENTS  DIFFERENTIAL  ENERGIZATION INHIBIT  ENERGIZATION INHIBIT FUNCTION to Enabled.  Make the following setpoint changes in the S4 ELEMENTS  DIFFERENTIAL  ENERGIZATION INHIBIT setpoints menu: ENERGIZATION INHIBIT PARMETERS: “2nd” HARMONIC AVERAGING: “Disabled” ENERGIZATION INHIBIT LEVEL: “15%” ENERGIZATION INHIBIT DURATION: “5 s” ENERGIZATION SENSING BY CURRENT: “Enabled” ENERGIZATION INHIBIT/MINIMUM ENERGIZATION CURRENT: “0.10 × CT”  Preset current with harmonic content just above the ENERGIZATION INHIBIT LEVEL used during the ‘energization period’.
