RTR introduces a new compensation system in its wide range of products, the SVG. This device is not only capable of power factor correction, but can also reduce harmonics to <5% THDI.
RTR’s advanced SVG is capable of generating a compensation current (same magnitude, but opposite phase) in real time to achieve desired power factor and can monitor harmonics up to 15th order thus improving power quality.
SVG working principle
• When the load draws inductive or capacitive current, it causes the current to lag or lead the voltage.
• The SVG detects the difference in phase angle and generates a leading or lagging current in the network, making the phase angle of the current almost the same as that of the voltage on the transformer side, which corrects the factor fundamental power to unity.
• The SVG draws harmonic current from the network in such a way that the magnitude of the current is the same as the harmonic current on the load side.
While its phase is opposite to that of the harmonic current on the load side, which ensures that the effective value of the harmonic current on the source side is reduced to a negligible level.
