Ooduleurs • Redresseurs • Batteries Capacitor bank without regulation known as fixed compensation • Used when reactive power to compensate is constant and when the load is working 24h / 24h. • Used when reactive power is to compensate for low power. Also standardized by the coefficient QC (Compensation to install in KVAR) / SN (Transformer power in KVA) is generally <15%. This threshold of 15% is indicative and we recommend it to avoid to overcompensate the charge power vacuum. • Used to directly compensate the asynchronous motor, load losses of the line head transformer. Table of the...

Onduleurs • Redresseurs • Batteries Capacitor banks with regulation also called automatic compensation • Used when the load changes on the installation and the need to compensate the reactive power is enabled through switched capacitor modules in or out sen/ice by the digital power factor controller Aunilec type RAUNI96 or RAUNI144 • Used for main switchboard (Low Voltage General Table) or from main departure of the factory • The power varying more or less rapidly can play an important role in choosing the automatic capacitor bank. - Either by electromechanical contactors if the rate of...

Onduleurs • Redresseurs • Batteries Industrial plants where the load varies greatly throughout normal operation will require automatic power factor controller in order to connect the necessary capacitive power. Why power factor should be improved? The benefits are the following: • Reduce utility charges • Increase system capacity • Improve voltage • Reduce circuit losses Reduce utility charges Thermal capacity considerations force the Utilities to overbuild its distribution system in order to serve a facility with low power factor. The Utilities force the customer to install capacitors...

Ooduleurs • Redresseurs • Batteries Operating conditions Nominal voltage The nominal voltage of the capacitor bank is the voltage at which the product was designed and to which the test voltages refer. For safe conditions, the operating voltage must not exceed the rated capacitor banks voltage. Working temperature Working temperature is a fundamental parameter for the safe functioning of Power Factor Correction Equipment. Consequently, it is very important to have sufficient heat dissipation inside the Power Factor Correction Equipment cubicle. Ventilation should be adequate to prevent that...

Power Factor correction in presence of harmonics In recent years. Power Factor Correction has evolved greatly due to the presence of generated harmonics by the loads. These loads produce harmonic currents and voltage which distorts the network waveforms. The main sources of harmonics are generated by AC/DC static converters and UPS systems. For these reasons it is essential that any installation of Power Factor Correction equipment must be carefully evaluated. The possible presence ot harmonic currents in the network could create conditions of parallel resonance between the inductance...
