Unit

Description

VoltageRatio

REAL

1.0

 

Scaling factor for voltage measurement, for adapting the raw values to the actual voltage (e.g. for voltage transformers).

VoltageInaccurateThreshold

REAL

0.3

%

Threshold value for the voltage measurement, below which the measured values are considered inaccurate or invalid.

VoltageInaccurateMode

ETcPowerInaccurateMode

SetZero

 

Defines the behavior for inaccurate voltage values (e.g. set to zero).

CurrentRatio

REAL

1.0

 

Scaling factor for the current measurement to adapt the raw values to the actual current (e.g. for current transformers).

CurrentInaccurateThreshold

REAL

0.3

%

Threshold value for the current measurement, below which the measured values are considered inaccurate or invalid.

CurrentInaccurateMode

ETcPowerInaccurateMode

SetZero

 

Defines the behavior for inaccurate current values (e.g. set to zero).

FrequencyNominal

REAL

50.0

 

Nominal frequency of the system (e.g. 50 Hz or 60 Hz) as a reference for frequency-dependent calculations.

FrequencyFilterTime1

REAL

0.1

 

Time constant of the first filter for smoothing the frequency measurement.

FrequencyFilterTime2

REAL

0.5

 

Time constant of the second filter for smoothing the frequency measurement.

EffectiveWindowCycles

UDINT

2

 

Number of grid half-waves used to calculate effective values.

HarmonicsWindowCycles

UDINT

20

%

Number of grid half-waves used for the analysis of harmonics.
