PRIYA CAPACITORS - SELF HEALING |
 |
When a breakdown occurs at a week point in the dielectric, an arc is struck between two |
| |
adjacent metal
coating in the immediate vicinity of the puncture evaporates very quickly and, |
| |
in doing so, extends the
length of arc. Both the impregnating agent and a tiny part of the |
| |
dielectric also decomposed in this arc,
and a zone of high gas-pressure is formed , which |
| |
forces the metal vapor condensation in the immediate
vicinity of the puncture. |
| |
This rise in pressure and the rapid increase in the length of the arc caused fast de-ionization at |
| |
the poing
of puncture, ensuring that the short-circuit current is generally interrupted within 5- |
| |
10 microseconds
irrespective of the amount of energy which is available. Apart from a small |
| |
puncture no other damage
occurs to the dielectric what so ever, and owing to the metal-free |
| |
zones which form, in the immediate
vicinity of the puncture, the insulation level of the |
| |
dielectric of the capacitor
then remains fully serviceable after one or even more such "self |
| |
healings". |

PRIYA CAPACITORS - VACUUM DRYING & OIL IMPREGNATION |
|
The assembled elements undergo vacuum impregnation Non-toxic, Non-hazardous, Non- |
| |
flammable, Non-
PCB, impregnate is used for impregnating. |

|
PRIYA CAPACITORS - VACUUM OIL FILLING |
|
capacitors are impregnated in vacuum tanks at controlled temperature under very fine |
| |
vacuum. Purified
Oil is allowed to flood in the impregnating chamber and the Oil automatically |
| |
gets filled in the capacitors
leaving no air space within the container to ENSURE BETTER |
| |
PERFORMANCE AND LONGER LIFE. |
