7.2.3 UNBALANCE AND ASYMMETRY

Imbalance is calculated by applying the Fortescue and Stokvis symmetric components method.

These values represent how imbalanced the facility is and the correct connection of the

phases.

These values are displayed on the screen as a %. The following variables are displayed on

the screen.

On this screen, the following options are shown above the function buttons:

Info: This displays the system information screen (Section 6.1.1.1., System Information).

Max: This displays the screen with the maximum values stored. The maximum values for each

variable recorded since the last reset are displayed on the screen along with the date

and time of registry.

On the Max screen, the INST. option appears, which can be used to return to the screen

that displays the instantaneous variables.

Min: This displays the screen with the minimum values stored. The minimum values for each

variable recorded since the last reset are displayed on the screen along with the date

and time of registry.

On the Min screen, the INST. option appears, which can be used to return to the screen

that displays the instantaneous variables.

kd U: Voltage imbalance coefcient.

ka U: Voltage asymmetry coefcient.

kd I: Current imbalance coefcient.

ka I: Current asymmetry coefcient.
