At the terminals of a heavily-loaded feeder cable. Where the kvar rating of the capacitors is less than, or equal to 15% of the supply transformer rating, a fixed value of compensation is appropriate. Above the 15% level, it is advisable to install an automatically-controlled bank of capacitors. Control is usually provided by contactors.

Automatic feeding of closures in filling lines is performed by systems. The main part of such systems is a hopper feeding device, which orients and delivers oriented three-piece caps to the closure position. Each hopper feeding device is intended only for a specific cap with certain dimensions and properties of its surfaces.
The developed mathematical model makes it possible to reliably determine the values of the capacity of the hopper feeding device with for a wide range of three-piece caps. Using the built mathematical feed rate model, it is possible to determine the optimal parameters of the hopper feeding device, at which the feed rate will be maximum.
Therefore, the main design step is to reliably determine the actual capacity of the mechanical disk hopper feeding device for each particular type of three-piece cap. The main functional elements of hopper feeding devices are the grasping and orienting elements.
