Q: How does a capacitor reduce
the consumption of energy on the large electrical motors
in my building?
Answer: A Micro controller closely monitors the
performace factors of a large motor to ensure that it is
not overheating or wasting energy. It gives a motor exactly
what it needs every millisecond so that it is operating
at maximum efficiency. Below are testimonials of test using
the Power Planner controller:
"I tested a Magnatech 3 Phase 20HP Hydraulic Pump
by Rexroth, with a nominal efficieny of 87.5%, 1740 RPM
on a 56T frame.
The values are quite revealing. A 40 volt drop in Voltage,
with no change in PEAK, and a 2 amp drop in current resulted
in a saving in WATTS. With the Power Planner engaged, the
voltage imbalance decreased and the power factor improved."
"The PPIII reduced power consumption by 18% and reduced
inrush current by 0.46 kiloamps, or 63%. Based on a power
replacement cost of $0.04 per kilowatt hour, the calculated
annual savings are $3,819.36, which equates to a material
payback of 5.81 months."
"I have tested a model 05145 Power Planner (460-480V,
250Amp) unit on an Ingersoll-Rand Rotary Reciprocating Air
Compressor using a Schlumberger Vectron Solid State Multifunction
Power Meter with Osaki Current Transformers.
When we run the I-R Compressor in the modulation mode it
consumed an average 106.42kWHR without the Power Planner.
With the Power Planner installed the average was 50.66kWHR.
This resulted in a 52.4% reduction in kWh consumption."
