Equalizer Activar The Activar is used for relatively stable loads such as commercial buildings, hospitals and data centers. The Activar is utilized for slow variations of reactive energy demand. The Equalizer is used for dynamic loads such as plastic injection/extrusion, auto industries, motor startup, port cranes and more. The Equalizer is utilized for fast or extremely fast variations of reactive power demand. Also available: Equalizer single phase and dual phase. While the structure of both systems is similar, the controllers are designed for real time controls and measurements for the Equalizer...

The Equalizer Power Quality Solution Definition Power quality is a term used to define any voltage, currentor frequency deviation which may result in failed equipment, process interruptions or power system inefficiency. These deviations can manifest themselves in harmonics, power factor, voltage sags/ swells, voltage flickering, transients and many other forms. The equalizer from Elspec is an all-in-one device designed to fix power quality issues. The equalizer is typically installed near the main service and major distribution panels. Voltage Sags (voltage Drops, Under –Voltage) Voltage sag,...

Applications Welding machines Spot welding loads fluctuate extremely rapidly and consume a large amount of reactive power. Due to high current changes generated by the near-instantaneous reactive energy consumption, large voltage drops are produced. These sags reduce welding quality and productivity. Additionally, these loads often create a high incidence of voltage flickering, which frequently exceeds recommended IEEE limits. Plastic injection Molding Due to widely varying unsynchronized load conditions, plastic injection molding applications have rapid and inconsistent reactive energy requirements....

Activar TRANSFORMER TRANSFORMER RR X XTR TR TR Resonance may occur on any frequency; however in most cases, current harmonic sources exist at the 5th, 7th, 11th and 13th harmonic. The Equalizer’s custom-designed reactors, used in series with the capacitors, prevent resonance by shifting the capacitor/network resonance frequency below the first dominant harmonic (usually the 5th) .

Switching module The switching module is comprised of solid-state switching elements that provide reliable, high-speed transient-free operation. Single, double or three-phase electronic switches, SCR/SCR or SCR/diode, are used for each capacitor group. Switching modules are specifically selected for each equalizer system based on the number of overall capacitor groups, current requirements and voltage rating. Cabinet Design Each equalizer system IP20/NEMA1 cabinet is made of steel sheet, with an epoxy powder coated gray (RAL 7032). Cabinet Options • Protection class upgrades (IP/NEMA) • Top-mounted...

Equalizer Activar Capacitor/Reactor Modules Iron Core Reactors Each Elspec equalizer includes high quality iron core reactors used in series with the capacitors. Each reactor is manufactured under tight control tolerance to ensure quality. It is built with a laminated, low-hysterisis loss iron core, copper windings, precision-controlled air gaps and class H insulation (180°C). Available reactor types: Inrush-only: Reactors are designed to limit the inrush current which may develop in the capacitor during power up, preventing thereby any damage to the switching elements, fuses and capacitors De-tuned:...

Equalizer- ST MEDIUM AND LOW VOLTAGE MOTOR STARTUP SOLUTION System Overview The EQUALIZER – ST is a real-time dynamic power compensation system that utilizes a proven industrial technology to provide an additional solution for the challenges related to large motor startups. The system itself operates at a low voltage and by utilizing a step-up transformer, the EQUALIZER – ST is also able to compensate medium voltage networks. The Electrical Challenge A motor start demands very high power for a relatively short period of time. The starting current of an AC motor usually varies from 6 to 8 times...

Equalizer- ST Mitigating Voltage Sags The most common cause of over currents leading to voltage sags are motor startup. One of the main design features of the EQUALIZER – ST is the ability to mitigate voltage sags during motor startup operations. As demonstrated in the diagram below, it is able to do so by injecting reactive power, for the given voltage sag magnitude at the required compensation period. This diagram includes a transformer [T] its impedance [XLT, RLT], an additional line [XL,RL] the EQUALIZER – ST [XC] and the load [RLOAD, XLOAD]. During a voltage sag the source input [Uo] drops...
