THD Voltages
and currents
In the Counters - Day -1 and Counters - Cumulative submenus some counters for harmonic
distortion are available:
Counts the total minutes that the total distortion exceeds the THD Threshold of the
currents
Counts the total minutes that the total distortion exceeds the THD threshold of the
voltages
NOTE: the counters saturate at 65535 minutes (45 days). It is possible to reset them
with a command from the service connector (via Ekip Connect) or with a communication
from the system bus

Count of THD Current referred to the last seven days of activity,
calculated using the unit's internal clock
