Definitions Of Terms Used

Power Conditioning System: A device that filters and conditions electrical power. It assists in eliminating power irregularities such as spikes, surges and other power anomalies. A power conditioning system is NOT a load controller or UPS (uninterruptible power supply).


Power Surge: Any increase over the proscribed voltage or power level as established by your electrical utility company for your facility. For example, a typical home uses 120/240 volt power. A voltage delivered to such a home in excess of 240 volts constitutes a power surge. Power surges cause unnecessary wear and tear on electrical equipment, reduce the operating efficiency of motors, and will often damage sensitive electronic equipment.


Power Spike: An extreme, short duration increase in power which is significantly beyond the intended voltage supplied by the power company. Spikes will usually damage sensitive electronic equipment and will often damage electrical equipment at your business or home.


Electrical Main(s): The point(s) at which your electrical power enters your facility. The power company’s electrical meter(s) is/are located at this “service entrance” point. If your facility has a large distribution cabinet )which contains your electrical meter) this cabinet is often referred to as the “main switchgear.” You usually receive a separate bill from the power company for each line of service (each electrical meter) at your facility. A power conditioning system installed at your electrical main (or each of your electrical mains, if you have more than one) can protect ALL of the electronic and electrical equipment in your whole facility from power surges and spikes, and will provide all of your equipment with clean, conditioned electrical power.


EMI/RFI: Electromagnetic Interference / Radio Frequency Interference – Such interference can disrupt the electrical power at a facility. High quality power conditioning systems help to filter out this interference, resulting in a cleaner, more consistent power flow. ALL of the industrial power conditioning systems provided by Western Watt include EMI/RFI filtering.


Harmonics: Just as when violin strings vibrates, it causes adjacent strings to start vibrating similarly, certain electrical signals in a circuit can set up harmonic signals within “adjacent” circuits. High quality power conditioning systems help to filter out these harmonics, resulting in cleaner power throughout a facility.


Power Factor Correction: The power factor (which is a fractional number between zero and one) is an indication of the efficiency with which electrical power is used to produce useful work by electric motors. Low power factors indicate that significant power is being dissipated in the power supply and distribution system. In the interest of reducing the losses in the distribution system, power factor correction is added to neutralize a portion of the magnetizing current of motors. Power conditioning systems incorporating capacitors in parallel with such motor circuits can sometimes improve the power factor to over a 0.9 or better. Some utility companies offer incentives for operating with high power factors, and some utility companies penalize certain customers with a poor power factor.


NOTE: Every Western Watt industrial Power Conditioning System includes surge protection, sine wave correction, EMI/RFI and harmonics filtering, and power factor correction.
