GOOSE Analogs that represent current, voltage, power, frequency, angles, or power factor can be used in a FlexEle-
ment. The following text must be used in the UNITS setting, to represent these types of analogs: A, V, W, var, VA, Hz,
deg, and no text (blank setting) for power factor.
GOOSE Analogs can be compared to other GOOSE Analogs with any character string or no string.
• GOOSE ANALOG 1 PU: This setting specifies the per-unit base factor when using the GOOSE analog input FlexAna-
log values in other T60 features, such as FlexElements. The base factor is applied to the GOOSE analog input FlexAn-
alog quantity to normalize it to a per-unit quantity. The base units are described in the following table.
The per-unit base setting represents thousands, not single units. For example, a PU base of 1.000 is actually 1000 and
a PU base of 0.001 is 1.
When using GOOSE Analogs and PU base in FlexElements, the largest value that can be displayed in the FlexEle-
ment actual values is 2,140,000.000.
The GOOSE analog input FlexAnalog values are available for use in other T60 functions that use FlexAnalog values.
