1 ReactiVar AT6000/AT7000 transient-free reactive compensation system nergy and cost savings benefits Power factor correction capacitors supply the reactive power (kvar) required by inductive loads. By correcting poor power factor ratings, capacitors reduce kva demand thus off-loading transformers, switchgear, and other equipment. The reduced kva demand results in lower utility power bills, cooler equipment operation, and longer equipment life. A growing number of utilities are charging for peak electrical demand in kva on each month s electric bill. As a result, customers are paying demand charges on both kw and kvar peak operating loads. Most utilities will offer an incentive to customers to keep efficiency high (measured by power factor) by reducing the kw and kvar usage, thus minimizing the demand charges. Transient-free reactive compensation (TFR) advantages Transient-free reactive compensation (TFR) systems are suitable for nearly all electrical networks and are ideal to correct poor power factor in electrical networks with a high concentration. of electronic loads. Traditional electromechanical contactor switching of capacitors generates voltage transients that can impair the operation of sensitive process equipment. apacitors are kept precharged at all times and connection to the network is performed when the capacitor precharge voltage matches the network voltage to achieve a transient-free switch. Transientfree switching also reduces wear on capacitors due to switching and will result in longer life for the overall capacitor system. This fact ensures longer life of the capacitor system and makes TFR systems ideal for almost all electrical networks. Depending on the level of harmonic producing (non-linear) devices on the network, two TFR systems are available: the AT6000 anti-resonant (detuned) system and the AT7000 filtered system. Note: Non-linear loads include variable speed drives, UPS systems, soft starters, and other power electronic devices. Make the most of your energy SM
