(47) AC-capacitors, Commutation and Damping Capacitors
Series KMKP/KA 900 V - 3500 V, higher voltages upon request. Capacitance range from 0.1 to 100 µF, in relation to rated voltage and dimension. Other capacitance values, upon request.
GENERAL Vishay ESTA Commutation capacitors are used in static frequency changers. They act, for example, as quenching capacitors taking over for a short time the current of the main thyristor thus making sure that the latter will safely block when the voltage returns.
The current load is very high on commutation and damping capacitors. Owing to the non-sinusoidal characteristic of the voltage path, high pulse-shaped recharge currents occur. With regard to ohmic and ...
(28) DC Capacitors Series GMKP 1000 V - 3000 V, higher voltages upon request. Capacitance range 1-400µF, in relation to rated voltage and dimension. Other capacitance values, upon request.
GENERAL VISHAY ESTA DC-capacitors may be loaded with a comparatively high component of alternating voltage or alternating current due to the low ohmic and low dielectric losses. Thus the capacitors can equally be employed for all DC applications.
The capacitors can also be applied as AC capacitors at a rated frequency of 50 Hz for the quoted root-mean-square voltages.
(6) The voltage limit of the bushings for the types of capacitor listed is based on the "Rules for Proportioning Clearance and Creepage Distances in Electrical Equipment", VDE 0110.
