PowerGUARD Energy Saving for inductive loads Saving 8%-15% Protection Power Quality

Even after multiple measures have been applied to dave energy, the majority of installations still use electricity in an inefficient way Since motors and other inductive loads represent 70% to 80% of the total installed power, the quantity of energy losses is still high. The losses do not only affect the electricity bill, but also the cost of raw material, labor and production. Electrical Losses within a site

The electrical installations, unknowingly, suffer from energy losses du to harmonics, over-voltage, transiants, phase unbalance and incompatible impedance. The effects of magnetic waves in a site are generally underestimated as a source to save energy. In the world of electricity all sites are looked by the energy source as a circuit having an inductance in series with a resistance – therefore looking at the problem “magnetically” seams very logical. PowerGUARD treats the entire system by reducing the magnetic fields and improving the power quality and the total consumption PowerGUARD considers the site as a simple inductive load. PowerGUARD reduces the impedance of the site and therefore improves the transport of energy and reduces consumption. Total Solution

The cause of low Power Factor is the presence of inductive reactance in the circuit. To improve the PF to 1.0, we can either add a capacitive reactance (Capacitor) or reduce the inductive reactance (PowerGUARD) A commun practice to improve the power factor ne pratique commune pis to add capacitors. This method reduces the quantity of reactive energy supplied by the source, but also can creates resonance in the circuit and increase the temperature of equipments and transformers by creating over-voltage situations Whereas PowerGUARD allows to produce savings that can be verified and at the same time increases the power factor and protects the equipments against surges of current and voltage.

PG Current generated in phase #1…. …is immediatly delivered to Phase #2…. …and to Phase #3, therefore neutralizing the Reactive current How PowerGUARD works By magnetic induction, a current is created and filtered to 60 HZ, this current is leading the voltage by more than 90 degrees, allowing it to flow to the opposite direction toward the source and neutralizing the reactive current

PowerGUARD benefits Voltage and current balancing Dynamic Power Factor correction Reduction of magnetic fields strength in the site Converting the energie created by overvoltage events to useful energy Equipments protection against surges Increases KVA capacity of Transformers Reduces the monthly bill
