English term or phrase: power conditioning device
Kontext:

Other components are also employed in the power system, including various loads and DC power sources. Examples of loads include various internal components (such as housekeeping loads, etc.), load drawn by external devices (such as lights, small motors, electronic devices, etc.) or ***power conditioning devices*** (such as capacitors, reactors, etc.). Examples of DC power sources include fuel cell systems, DC machines (driven, for example, by a combustion engine), capacitors and batteries. Some types of DC power sources are configured to both provide and store electric energy. Other types of DC power sources are configured to non-renewable fuel energy sources into electric energy

Ich brauche einen - zumindest erläuternden - deutschen Begriff.

Vielen Dank für Eure Hilfe im Voraus!

Explanation:
A power conditioning device protects sensitive electronics in modern electronic equipment from disruption or destruction caused by transients which can cause both induction and injection currents into the grounding system of the electronic equipment. This device nominally comprises an isolation transformer and a ground impedance between the earth ground connection from a distribution panel and the safety ground connection to the powered equipment.

Most of the Production processes are very sensitive to reduced power quality,such as harmonics or short interruptions.Such loss of power quality results in financial losses. This situation can be prevented by installing a combination of power conditioning device and UPS(Uninterruptible Power Supply system).
...
One best method is ACTIVE filters, but they are very costly. Cheap are Series blocking or parallel filtering.
..
You are right. Use of any electronic oscillators produce harmonics. But we have to use them when required. So Harmonic suppressor has to be incorporated with those equipments to have quality power.

Power Conditioning Devices beeinflussen die Form und Größe von Spannung und Strom (Frequenz, Oberwellenanteil, Phasenverschiebung, Effektivwert, usw.)

What is a UPS?
A UPS (uninterruptible power source) is a secondary power source to use in the event of power failure. It has the ability to continue delivering power in the event that the primary source is not working. The size and complexity of the UPS system determines what are acceptable levels of power. UPS systems come in various sizes and functions.

What is AVR and why is it important?
All of the Energizer UPS units include AVR. A UPS system that features "AVR" (automatic voltage regulation) will correct the voltage if it is over or under the normal levels. "Buck" refers to the lowering of voltage and "boost" refers to the raising of voltage.

A passive filter is a kind of electronic filter that is made only from passive elements -- in contrast to an active filter, it does not require an external power source (beyond the signal). Since most filters are linear, in most cases, passive filters are composed of just the four basic linear elements -- resistors, capacitors, inductors, and transformers.
http://en.wikipedia.org/wiki/Passive_filter

An active filter is a type of analog electronic filter, distinguished by the use of one or more active components i.e. voltage amplifiers or buffer amplifiers. Typically this will be a vacuum tube, transistor or operational amplifier.

Active filters have two main advantages over passive filters. The first is that the amplifier powering the filter can be used to shape the filter's response, e.g., how quickly and how steeply it moves from its passband into its stopband.
..
There are several varieties of active filter. Some of them, also available in passive form, are:

High-pass filters – attenuation of frequencies below their cut-off points.
Low-pass filters – attenuation of frequencies above their cut-off points.
Band-pass filters – attenuation of frequencies both above and below those they allow to pass.
Notch filters – attenuation of certain frequencies while allowing all others to pass.

A power conditioner (also known as a line conditioner or power line conditioner) is a device intended to improve the “quality” of the power (see power quality) that is delivered to electrical load equipment. While there is no official definition of a power conditioner, the most common usage of the term refers to a device that acts in one or more ways to deliver a voltage of the proper level and characteristics to enable load equipment to function properly.
..
The terms “power conditioning” and “power conditioner” are misnomers, however they have been accepted in common usage to convey an image to those not intimately familiar with electrical theory. It is voltage rather than electric power that is being acted upon, and “conditioning” is actually the control and adjustment of the voltage.

In jedem Fall handelt es sich um Bauteile mit frequenzabhängigen Eigenschaften (Kondensatoren, Spulen, Filter).

Der Blindwiderstand (auch Reaktanz) ist eine Größe der Elektrotechnik, die bei Wechselstrom eine Phasenverschiebung zwischen Spannung und Strom verursacht. Der Wert des Blindwiderstandes ist frequenzabhängig.
..
Folgende Verbraucher sind in der Regel ohmsch-induktiv:

Elektromotoren
Transformatoren
Leuchtstoff- und Gasentladungslampen mit konventionellem Vorschaltgerät, wenn nicht kompensiert
Schütze
Folgende Verbraucher sind in der Regel ohmsch-kapazitiv:

Schaltnetzteile ohne PFC (u. a. viele Computernetzteile)
Frequenzumrichter ohne PFC
Leuchtstofflampen mit einer Reihenschaltung aus Drossel und Kondensator (verwendet zur Blindstrom-Kompensation weiterer Leuchten ohne diese Reihenschaltung)

Induktivitäten und Kapazitäten werden gemeinsam als Reaktanzen bezeichnet.

Vielen Dank, auch für all die Mühe bei Deinen Antworten. Ich verlasse mich - wenn auch zugegebenermaßen irgendwie mit einem leicht unguten Gefühl, weil sich mir das nicht erschließt - auch hier auf Deine Erfahrung. Vorsichtshalber mache ich eine Anmerkung für den Kunden.
