 | Pha... High Voltage Power Capacitors
In the case of single phase capacitor units with dead casings, both polarities are led out through the casing in an insulated condition by means of porcelain bushings.
In the case of single phase capacitor units with one bushing only, the second polarity is connected to the casing.
Three-phase capacitors are provided with three bushings for connection to the phases and have dead casings with grounding connection point . They are connected either in star or in delta.
In cases where protection against an accidental touch is required, the capacitors can be supplied as IP 55 version.

 | Standard AC Capacitors, Oil Impregnated, Self-healing, with Fuse
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 dielectric losses, the commutation capacitors have to be of a particularly high quality. Since modern low-loss dielectrics are applied and also the current paths are generously dimensioned, Vishay ESTA commutation capacitors are ideal for such extreme loads. |
| Standard DC Capacitors, Oil Impregnated, Self-healing, with Fuse
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. |
