Example: if each 15 minutes the power keeps constant in 4kW, a demand
registered
in the interval will be of 4 kW, assuming that Delta_t be configured for 15
minutes. At the end of 1 hour will be registered a demand of 16kW.
7.8. PHASE SEQUENCE
In this screen are showed:
TN
Sequencia Fase = Sequence Phase
Ligacao: Estrela = Connection: Star
Frequencia = Frequency
I Neutro = I Neutral
Phases sequence: When shows "123" the sequence is correct, otherwise will be
showed ">>>".
Connection: Shows the connection type configured in the PowerNET P -600.
Frequency: is calculates utilizing as reference the phase 1 of the electrical
system.
I Neutral: is the sum of the system currents. In balanced systems this current
must be zero or next to zero. The equipment calculates this current by the factors of
currents 1, 2 and 3.
7.9. THD
In this screen is showed the percentile of THD (Total Harmonic Distortion) of
tension and current in each phase:
v Utilize the increase or decrease keys to visualize the other harmonics.
Obs.: To enable the calculus of THD and Harmonics, at least one of the harmonics
blocks orTHD must be configured in the equipment memory.
