Description
Instantaneous currents are real time measurements of earth fault and phase currents.
Representations and access pages
The current measurements are available in different representations, accessible from the
following pages:
• Histograms page: graphical representation in the form of a histogram of the phase
currents, and measurement in Amperes of the highest current.
• Measuring instruments page: graphical representation in the form of an ammeter and
measurement in Amperes of the highest current.
• Measurements page: measurements in Amperes of all the phase currents and earth
fault current.
NOTE:
• The measurement of the earth fault current is available only with LSIG versions of
releases.
• The measurements in Amperes are available from a minimum value of 0.03 In for
the phase currents, and 0.08 In for earth fault current. For lower currents "..." is
shown.
• In the Histograms page, the graphical representation of the currents is in relation
to 1 In, with a maximum value of 1.25 In
