Having three sets of historical logs provides you with the option of

programming each log with unique parameters. For example, you can program

Historical Log 1 to record measured values parameters (for example, Frequency,

Voltage, Current), Log 2 to record energy values parameters, and Log 3 to record

power quality parameters. Historical Log parameters can be selected from the

following thirteen groups:

• Real-Time Metering (Frequency; Instantaneous Voltage; Instantaneous Current;

Total and Per Phase Power and Power Factor; Neutral Current ; unbalance V/I;

load type; Current demand; and Per Phase/ Total Power demand)

• Energy (Ep_imp; Ep_exp; Ep_total; Ep_net; Eq_imp; Eq_exp; Eq_total; Eq_net; Es;

Epa_imp; Epa_exp; Epb_imp; Epb_exp; Epc_imp; Epc_exp; Eqa_imp; Eqa_exp;

Eqb_imp; Eqb_exp; Eqc_imp; Eqc_exp; Esa; Esb; Esc)

• Sequence Component (positive, negative and zero sequence)

• Phase Angles(the angle between U1 and other voltage and current parameters.)
