How does Electroflow™ react to changes in load?
The ElectroFlow™ unit samples voltage, amperage, power factor, and current threshold. The sampling rate of an ElectroFlow™ unit is from 3840 samples per second all the way up to 15000 samples per second. This sampling is handled by Motorola HC series microprocessors.
Dependent upon sample results, the regulator calls for different stages and different configurations and different hybrid configurations of the internal stages to address a particular
problems. The unit then reads again to see that the steps it took corrected the inefficiencies.
If the problem was not corrected, the system samples and reacts again.
The ElectroFlow™ unit works with the plant’s electrical load. As the load changes, the performance of the system changes. The more problems there are, the more the system will activate the various stages. The less the load, the fewer stages the system will bring on and off line.
How can Electroflow™ Optimise Power Quality operating in parallel?
This can only be accomplished by having multiple impedances in the electrical system. There are three levels of impedance, designed to address the problems of the facility – lower, equal to load, and
Lower impedance introduces a path of least resistance to filter harmonics, surges, transients, spikes, and other variances which may affect the facility. If the impedance is lower, according to Kirchoff’s Law, all the problems will enter the ElectroFlow™ unit before the facility’s loads.
A load/equal impedance to the facility’s electrical system is able to correct imbalanced conditions based on X/R ratio and z factor. A higher impedance than the facility’s electrical system impedance allows the stabilization of the voltage. This design set up of the ElectroFlow™ system allows the correction of multiple problems at once, which results in energy savings and power quality.
Will my load be jeopardised if Electroflow™ fails?
ElectroFlow™'s multistage system is triple protected with each stage independently monitored, protected, and activated. Each stage stands by itself. This is a great advantage in the rare case of any failure of any components. Each stage will isolate itself, and the remainder of the system will continue to deliver its functions. In 98% of cases, the entire system is connected to the distribution in parallel, ensuring that it will not disrupt the plant’s operation.
Can one Electroflow™ unit address all the inefficiencies on a transformer?
Yes, in many cases it can. If a specific problem occurs downstream at a sub-feeder, for more effectiveness and for economic reasons, a unit will be installed onto that particular feeder. This will only be done if the load profile of the facility’s load exceeds the standard design criteria. This will isolate the specific problem(s) at the specific load feeder and filter them out so the common buss will not be affected, and the losses associated between the feeder and the main distribution will be eliminated.
Is Electroflow™ suitable for all facilities?
The system is sized for three phase systems operating from 208 volts to 345 kilovolts regardless of the line frequency (40Hz to 400Hz). The largest current system installed is for a load of 300 Megawatts. A good guide as to whether ElectroFlow™ would be suitable for your facility is whether or not you are served by one or more transformers.
