SDr filter reactor series

SDr low-voltage reactive power compensation reactor, also known as tuning reactor or filter reactor, is generally used in series with the capacitor, used in power reactive power compensation system, to achieve the target induced current. The product can be tuned to a certain resonance frequency to absorb the harmonic current in the power grid, making it capacitive at a certain frequency, preventing parallel resonance and harmonic current from flowing into the capacitor, causing amplification, thereby improving the power factor and ensuring reactive power compensation The normal operation of the system.
