خازن های ولتاژ بالا به نوعی خازن اطلاق می شود که از یک بوش سرامیکی، یک گروه عنصر خازن و یک پوشش تشکیل شده است.خازن های ولتاژ بالا دارای ویژگی های کم افت و وزن سبک هستند. Individual Power Factor Correction The power factor correction capacitor is connected directly to the terminals of the consumer and will be switched together with it. The advantages of this method are: Relief of the conductor s and switches, no capacitor switches or discharge resistors are needed, and the installation is simple and cheap. The individual compensation is the best solution for large consumers (e.g. motors), particularly if they are in continuous operation. Individual Power Factor Correction of 3-Phase Motors The motor and the capacitor are connected in parallel. They are both switched in and out by means of one and the same switchgear and also monitored by a common protective device. A discharge device is not required, because discharging takes place through the motor windings. The switchgear must be rated to be capable of withstanding the inrush current of the capacitor and the connection s must be capable of withstanding the full load current of the motor. The capacitor, in this case, has to be installed in close proximity to the motor.
