负无功功率继电器：负无功电平检测可以禁用，用作报警或过程控制。如果不需要此功能，则将此设置点设置为关闭。当负无功功率水平超过所选水平时，选择报警继电器将使报警继电器激活并显示报警信息。选择辅助继电器将使辅助继电器在设定的负无功功率水平下激活，但不会显示任何信息。这用于过程控制。•负无功功率水平：当三相无功功率等于或超过此设置点设置的水平时，将出现过多的负无功状态。•负无功功率延迟：如果负无功功功率等于或超过此设置点中编程的时间延迟的负无功电平设置点值，则会出现过大的负无功率条件。
NEGATIVE REACTIVE POWER RELAY: Negative reactive power level detection can either be disabled, used as an alarm or as a process control. Set this setpoint to off if the feature is not required. Selecting alarm relay will cause the alarm relay to activate and display an alarm message whenever a negative reactive power level exceeds the selected level. Selecting auxiliary relay will cause the auxiliary relay to activate for a set level of negative reactive power but no message will be displayed. This is intended for process control. • NEGATIVE REACTIVE POWER LEVEL: When the three phase reactive power equals or exceeds the level set by this setpoint, an excess negative reactive power condition will occur. • NEGATIVE REACTIVE POWER DELAY: If the negative reactive power equals or exceeds the NEGATIVE REACTIVE POWER LEVEL setpoint value for the time delay programmed in this setpoint, an excessive negative reactive power condition will occur.
