The power quality function CMHAI1 is used to measure the harmonic contents of the phase current.
The power quality function VMHAI1 is used to measure the harmonic contents of the phase voltages.
The power quality function PHQVVR1 is used to measure the voltage variation, that is, sags and swells.
The voltage unbalance power quality function VSQVUB1 monitors the voltage unbalance conditions in power networks. It is used to monitor the commitment of power supply utility of providing a balanced voltage supply on a continuous basis. VSQVUB provides statistics which can be used to verify the compliance of the power quality.
The above functions are included in default configuration for demonstration purposes only, but not configured by default. The functions can be configured as needed.
