POWER QUALITY

Power quality usually degrades within your facility because of the manner in which power is utilized by your loads. For example, electronic loads such as lighting ballasts, Variable Frequency Drives and computer power supplies, generate harmful harmonic signals while motors and other inductive or capacitive loads create power factor problems. Each combination of loads creates unique issues that must be corrected for efficient operation of your facility. PROXYPQ solves the problems caused by the different loads in your facility and restores efficient power quality.

PROXYPQ APPLICATIONS

CAPACITOR BANKS

Capacitors, either fixed bank or switching, have always been used to generate VAR and correct power factor. This approach worked well before electronic devices and the harmonic distortions they cause became so prevalent. In today’s harmonically rich environments, capacitors attract harmonics to themselves creating excess heat, over voltages and harmonic resonances that often lead to major electrical system failures and out of control maintenance costs. PROXYPQ generates VAR while mitigating the harmonic problems caused by today’s high-efficiency electronic devices. Power factor problems, harmonic distortions and excess heat are no longer a problem with PROXYPQ.

HARMONIC FILTERS

The growing prevalence of harmonic distortion in today’s electrical systems has sparked the development of device-specific harmonic filters. These filters might protect the specific device they are a part of but they are ineffective at reducing system harmonics. In fact, multiple filters will often interact with each other and actually magnify the system harmonic and power factor problems. This can be extremely damaging to unprotected devices. PROXYPQ corrects power factor and addresses the harmonics problem at a systemic level. This eliminates harmonic resonance problems while also protecting specific devices, such as your VFD’s, so you will no longer need to spend extra money for additional filters.

THE PROXYPQ SOLUTION

PROXYEM's PROXYPQ is a load side device that will nullify almost all harmful harmonics on your electrical system. PROXYPQ also has the ability to generate Magnetic VAR as needed by the system to correct power factor issues. This state of the art process brings your power to near unity and allows for your facility to run the way it was designed. PROXYPQ also dampens rapid voltage fluctuations and helps maintain voltages within specified parameters while mitigating the damaging effects that poor power quality has on your valuable equipment. We are the only true power solution.

PROXYPQ FEATURES

MAGNETICVAR

PROXYPQ allows for distributed magnetic var as needed to balance power factor, thus providing the force required to keep energy flowing efficiently through a facility. This enhances the the buildings ability to provide clean, full-featured power at all distribution points.  Traditionally VAR has been enhanced through the use of capacitor banks. Unfortunately, capacitors tend to attract harmonics and amplify their harmful effects.  PROXYPQ's magnetic VAR solution eliminates the problem of harmonic amplification while providing full-featured VAR enhancement.

HARMONICs MITIGATION

As non-liner loads have increased, the harmonics associated with these non-liner loads have increased and are magnified by the presence of capacitor banks.  Capacitors attract harmonics and magnify their harmful effects on the system resulting in higher voltage levels, voltage irregularities, higher heat levels, and increased equipment failure along with capacitor bank failures.  PROXYPQ harmonic mitigation technology reduces harmful harmonics to safe levels.

VOLTAGE REGULATION

Voltage regulation describes the ability of a system to provide near constant voltage over a wide range of load conditions.  Utilities generally have very little monitoring equipment.  Couple this with today’s complex resource management issues and you have voltages that are constantly changing. This constant fluctuation makes it difficult for utilities to make the adjustments necessary to keep voltage levels within operating limits.  PROXYPQ dampens rapid voltage fluctuations and helps maintain voltages within specified parameters.
