Prima Line Load Reactor Pdf Multiple drives or inverters on a common power line require one reactor per controller. individual reactors provide filtering between each controller (reduce cross talk) and also provide optimum surge protection for each unit. It is desirable that the reactor does not go into magnetic saturation during a short circuit, so generally an air core coil is used. at low and medium voltages, air insulated coils are practical; for high transmission voltages, the coils may be immersed in transformer oil.
Cos Phi Line Load Reactor Applications The following figure illustrates the variations of the cos φ indicator (with the definition of the cos φ min max) and its value according to ieee convention for a receiver application:. Though using line and load reactors can protect the vfd systems, and increase the reliability and robustness, users should be aware of some side effects such as adding cost and weight, requiring space, generating heat and reducing efficiency. It is desirable that the reactor does not go into magnetic saturation during a short circuit, so generally an air core coil is used. at low and medium voltages, air insulated coils are practical; for high transmission voltages, the coils may be immersed in transformer oil. Using cos phi mode trainer is an effective method to optimize the power factor in the electrical system. with this technology, monitoring, analysis, and adjustment of phase angle can be carried out to minimize reactive power and improve the efficiency of active power use.

The purpose of this document is to provoke some thought on the part of the person(s) responsible for the successful installation of the drive, and to provide some guidelines as to if, where and when a reactor is needed and what size reactor to use. A higher impedance translates directly into lower harmonic currents, but of course also into a larger component with a higher voltage drop − and vice versa. 4% impedance reactors like rwk 212 provide an excellent cost benefit ratio and are particularly beneficiary in the most diverse motor drive applications. The name “line reactor” immediately brings to mind that this inductive device is used on the line (input) side of the vfd. however, that same or de rated line reactor can often be used on the load (output) side of a vfd as it delivers power to the motor. Most of the consumer’s installations take active and reactive power from the electrical network. the active power is converted into mechanical power, while the reactive power is needed to establish and remove the magnetic fields of motors, transformers and reactors.
