Reduced Demand Charge
Most electric utility companies charge for maximum metered usage based on either the highest registered demand in kilowatts (KW meter), or a percentage of the highest registered demand in KVA (KVA meter), whichever is greater.
If the power factor is low, the percentage of the measured KVA will be significantly greater than the KW demand.
Improving the power factor with the use of the SP1000 will therefore lower the demand charge, helping to reduce your electricity bill.
Increased Load Carrying Capabilities in Existing Circuits
Loads drawing reactive power also require reactive current. Installing the SP1000 at or near the inductive loads reduces the current carried by each circuit. This reduction in current flow resulting from improved power use which can allow the circuit to carry additional loads, saving the cost of upgrading the distribution network when extra capacity is required. This can save your company thousands of dollars in unnecessary upgrade costs. In addition, the reduced current flow reduces resistive losses in the circuit.
A lower power factor causes a higher current flow for any given load. As the line current increases, the voltage drop in the conductor increases. This can result in a lower voltage at the equipment. With an improved power factor, the voltage drop in the conductor is reduced, improving the voltage at the equipment.
Reduced Power System Losses
Although the financial return from conductor loss reduction alone is seldom sufficient to justify the installation of capacitors, it is sometimes an attractive additional benefit; especially in older plants with long feeders or in field pumping operations. System conductor losses are proportional to the current squared and, since the current is reduced in direct proportion to the power factor improvement, the losses are inversely proportional to the square of the power factor. This leads to better overall system efficiency.
Reduced Carbon Footprint
By reducing your power system’s demand charge through the SP1000, your company is putting less strain on the electrical grid, therefore reducing its carbon footprint. Over time, this lowered demand on the electrical grid can account for hundreds of tons of reduced carbon production, all thanks to the improvement of your power system’s electrical efficiency via the SP1000.
All electrical motors have efficiency curves, that are the relationship between RPM, Torque and Power consumed. This curve will always have a point at which the efficiency is maximized. A higher power factor means that the current and voltage present in power lines are better synchronized; therefore the pulsating torque that is used to create torque is more uniform. In other words, “the road you drive on has fewer bumps”; and this will push the motor curve closer to its optimized efficiency point.
High frequency harmonics present in most power lines do to non-linear power consumption cannot be used by inductive loads. Industrial motors are designed to run at 50 or 60 Hz frequencies. Any frequency that is not in this range cannot be used to power the motor. Having cleaner power due to the reduction of Harmonics and reduction in Wave Distortion will increase the motor efficiency and produce less heat in the motor.
Reduce Negative Energy
Negative energy is the energy that is returned to the power company due to the fact that it is in the wrong phase. This Energy will have to travel back to the closest low impedance point, which is usually on a pole or transformer outside of facility. There is obviously a cost associated with this double transmission, which is usually part of the demand charge.
The SP1000 will identify the optimum point of use, which will minimize the imbalance in your power panel.
Since the power transformer supplying the power to the facility will run more efficiently when the power is balanced, any reduction in imbalance will reduce energy transmission, and therefore lower demand charges.
Optimize Power Utilization
Power utilization is the way power is consumed in your facility. The SP1000 can help you manage your electric demands by identifying the best times to operate your largest electrical loads .
Reduce Neutral Line Return Current
Any imbalance in a 3 phase circuit will cause some amount of current to be returned in the neutral line. This current will have to travel back to the lowest impedance point which is normally some distance away from the facility. The SP1000 will create this low impedance point, therefore the cost of transmission will be less.
Help Identify Maintenance Issues
Data Acquisition System built in the SP1000 is used to identify abnormal usage of electricity. This information can predict costly failures before they occur.
Visualize System Parameters
The SPIDER display program with the SP1000 has many features that help to visualize complex system parameters and show areas where there is a need for attention and correction.
Access Data Remotely
The SPIDER program allows you to remotely access your systems activities via internet to retrieve data and the systems status.
Reduce System Wear and Tear
Any increase in efficiency of a motor by way of power efficiency, or lower pulsating torque will reduce heat on bearings and therefore extend motor life.
