负实际功率继电器:负实际功率电平检测可以禁用,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。选择报警继电器将使报警继电器激活,并在负实际功率水平超过所选水平时显示报警信息。选择辅助继电器将使辅助继电器在设定的负实际功率水平下激活,但不会显示任何信息。这用于过程控制。•负实际功率水平:当三相实际功率等于或超过此设定点设置的水平时,将出现过大的负实际功率条件。•负实际功率延迟:如果负实际功率等于或超过此设置点中编程的时间延迟的负实际功率电平设置点值,则会出现过大的负实际功耗情况。
NEGATIVE REAL POWER RELAY: Negative real 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 real power level exceeds the selected level. Selecting auxiliary relay will cause the auxiliary relay to activate for a set level of negative real power but no message will be displayed. This is intended for process control. • NEGATIVE REAL POWER LEVEL: When the three phase real power equals or exceeds the level set by this setpoint, an excess negative real power condition will occur. • NEGATIVE REAL POWER DELAY: If the negative real power equals or exceeds the NEGATIVE REAL POWER LEVEL setpoint value for the time delay programmed in this setpoint, an excessive negative real power condition will occur.
