Coupling When designing capacitors into DC blocking and coupling applications, a suitable capaci-tance value must first be selected in order to meet the primary requirements of the design. The most essential capacitor parameters to evaluate for these applications are series res-onant frequency (F SR), magnitude of imped -

Customer ServiceCoupling Capacitors A coupling capacitor (C C) is a very common coupling method when performing a PD measurement as described in the IEC 60270 standard. When a partial discharge event occurs, the coupling capacitor provides the devices under test (DUT) with a displacement current, which is measurable at the coupling devices (CPL). Such an

Customer ServiceWhen selecting a capacitor for coupling/DC blocking applications, the key parameters to consider include impedance, equivalent series resistance, and series resonant frequency. The capacitance value primarily depends on the frequency range of the application and the load/source impedance.

Customer ServiceCoupling capacitors are used for the decoupling of PD current pulses together with measuring impedances placed in series in standard measuring circuits to convert into voltage pulses for analysis with a PD detector according to IEC 60270. The coupling capacitor also acts to drop the test voltage to a safe, measurable value.

Customer ServiceCapacitors used in coupling and dc blocking applications serve to couple RF energy from one part of a circuit to another and are implemented as series elements. Proper selection of coupling capacitors insures the maximum transfer of RF energy.
Customer ServiceDividers/Coupling capacitors can be extended by a blocking impedance to act as a PD filter. Of course the capacitors are capable to withstand transient voltage stresses in case of flash overs. All dividers/coupling capacitors can be equipped with any type of PD measurement equipment acc. to IEC 60270.

Modern medium-voltage power distribution system supply a large number of reactive loads, which lead to plenty of side-effects, such as uncontrolled reactive power, poor power factor and significant point of common coupling (PCC) voltage fluctuation [1, 2].The distribution static synchronous compensator (DSTATCOM) system is an essential
Customer ServiceThe Coupling Capacitor is a highly sensitive partial discharge (PD) sensor used to decouple PD from the monitored conductor. Coupling Capacitors are installed as close to the winding as possible for maximum sensitivity. Applications include generators, switchgear, motors, Iso-phase bus and transformers.

The days of single supply amplifiers with large electrolytic coupling capacitors are now almost over, although there are still a few small low power amps that are built that way. Because these amplifiers are almost invariably considered ''lo-fi'' and will normally drive small speakers in horrible small plastic boxes
Customer ServiceCoupling capacitors (or dc blocking capacitors) are use to decouple ac and dc signals so as not to disturb the quiescent point of the circuit when ac signals are injected at the input.
