Fixed power factor correction Automatic power factor correction Capacitor Bank Switching - General Reminder of capacitor transient conditions In Low Voltage industrial installations, capacitors are mainly used for reactive energy correction (raising the power factor). When these capacitors are energized, overcurrents of high amplitude (up to 180 In) and high frequencies
Setting the cabinet(s) in place. Connecting the assembly to the electrical system. Installing the current transformer (CT) on the system (checking CT polarity) and terminating secondary in the unit. Programming the controller. Starting and ensuring proper operation.
Detuned Capacitor Banks are automatic capacitor banks made of several capacitor steps controlled by a power factor (PF) controller. They are able to adjust PF to any value between 0.8 lagging and unity. When the PF differs from the target setting for more than 1 second, the capacitor switching modules switch stages as needed to bring the PF as

Function of capacitor bank. The main function of the capacitor bank is to improve the power factor (cos phi coefficient) in order to reduce the unworked power (also known as reactive power). <3Introduction of capacitor bank. Cos phi capacitors aka reactive power compensation cabinets usually install capacitors in parallel with the load, controlled by a controller Capacitor control

From the main screen, press the ( right / Enter) key to enter the Measurement mode. See menu map for a list of designated parameters. Press the (left / esc) key to return to the main screen that displays the existing PF. The final programming step is to verify the working of the capacitor bank.
If the storage area is cool and/or damp, space heaters should be provided to prevent condensation inside the Automatic Capacitor Bank. Evaluate and if necessary clean the dust/air filter. For NEMAT 3R units, NEMA 3R rating only applies once independent sections have been connected and the unit has been completely assembled.
To check the capacitor stages, switch the controller into the INFO mode by pressing the ▼ (down) key. In the INFO submenu, by pressing the ▲ (up) or ▼ (down) key, the steps can be chosen and once the steps are indicated in the display, pressing the ( ) (right/enter) key displays the information for the selected steps.
The CT should always be installed upstream of the loads and capacitor bank. CT shall not be installed on the feeder feeding the capacitor bank. CT polarity must be observed accurately for proper functioning of the capacitor bank. H1 should always face the source (utility) side. See Figure 1.
The trip settings on the circuit breakers shall be set in accordance with the NEC and coordination requirements within the facility. The PXM 1300 provides an electronic panel meter to those who wish to monitor various electrical parameters of the capacitor bank.
To switch the controller in manual control mode, press the ▼ (down) key to step through the “INFO” mode to “MANUAL” mode. Press and hold the ( right /Enter) key for approximately 3 seconds until “1” displays, indicating the stage number 1 is available for control.
