Load reactors are used on capacitor banks to prevent resonance and used on the output of AC Drives to reduce the effects of high motor wiring capacitance and to “soften” the dv /dt (high rates of change of voltage) applied to the motor windings. - Efficient reduction of high output voltage dv/dt from IGBT motor drives (as per DIN VDE 0530) - Restriction of over voltages caused by line reflections on motor cables (as per DIN VDE 0530) - Protection of motor coil insulation from premature aging and destruction - Significant increase of service life of electric motors - High reliability and production up time for mission critical applications - Less interference propagation towards neighboring equipment or lines Bornika is the exclusive agent of Schaffner and ZEZ Silko in the fields of consultation , sales and distribution of power industry products including Load Reactors .
Product list of Load Reactors
Very frequent use of electronic devices with non-linear waves leads to a distortion ofsinusoidal voltage and current now.Distortion of sinusoidal harmonic waves has resulted in current increase of power capacitors and other parts of the system as well as the possibility of capacitor resonance with other inductive loads (transformer ). As a result of these phenomena it can lead to the destruction of all components used in power factor correction devices.The solution is the use of detuned (protection) reactors forming a series resonant circuit with capacitors (typically 189 Hz) . Reactors connected with capacitors prevents unnecessary resonance and also acts as a broadband filter. Mostly it is appropriate to use the reactors when the voltage distortion THDu is more than 3%.
