•正无功功率继电器：可禁用正无功电平检测，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。当正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激活设定的正无功功率水平，但不会显示任何信息。这用于过程控制。•正无功功率水平：当三相无功功率等于或超过此设置点设置的水平时，将出现过多的正无功状态。•正无功功率延迟：如果正无功功功率等于或超过该设置点中编程的时间延迟的正无功电平设置点值，则会出现过大的正无功率条件。
• POSITIVE REACTIVE POWER RELAY: Positive 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 positive reactive power level exceeds the selected level. Selecting auxiliary relay will cause the auxiliary relay to activate for a set level of positive reactive power but no message will be displayed. This is intended for process control. • POSITIVE REACTIVE POWER LEVEL: When the three phase reactive power equals or exceeds the level set by this setpoint, an excess positive reactive power condition will occur. • POSITIVE REACTIVE POWER DELAY: If the positive reactive power equals or exceeds the POSITIVE REACTIVE POWER LEVEL setpoint value for the time delay programmed in this setpoint, an excessive positive reactive power condition will occur.
