3.) Determination of pulse valence
The energy, which is consumed within 1 hour
can be calculated as:
Energy = Real power * time
Energy = 400kW *1h
Energy = 400kWh
If a pulse valence of 400kWh per pulse is set,
the UMG96S transmits one pulse per hour at full
load, which corresponds to a pulse frequency of
= 1 pulse/h
= 1 pulse/3600Sec.
= 1/3600 Hz
= 0,00028 Hz
With this pulse valence, very few pulses are
transmitted. Supervision of energy in the range
of minutes is not possible.
But UMG96S can provide up to 10 pulses per
second (10Hz), and the data collecting device
can detect 50 pulses per second (50Hz). A pos-
sible solution is to programm the UMG96S to
send a frequency of 10Hz at 400kW (or for
safety reasons 500kW).
= 500kWh
Energy per hour
= 500kWh / 3600
= 0,14kWh
= 140Wh
Energy per second
= 140Wh / 10
= 14Wh
Energy in 1/10 sec.
This means, if 10 pulses are sent per second
with a valence of 14Wh, this corresponds to the
power of 500kW for one hour.
