INTRODUCTION
All PP Capacitors have been developed to overcome the limitations of MPP Capacitors.
1. In such current due to frequent Switching.
2. Current handling Capacity, because of presence of Harmonics in the Electrical
Systems.
Development in modern technology have led to a significant increase in the
number of thyristor & converter fed loads & D.C. Drives. unfortunately
the said equipment's have undesirable Effects on the incoming AC supply, drawing
appreciable inductive reactive power & a non-sine-wave current, The Standard
range MPP Capacitors are designed for systems where harmonics are not present.
The rising capacitor is accommodated by constructional improvement of Jaivic all
PP Capacitors.
Salient Features of JAIVIC ALL PP Capacitors
1. It is two layer film design. Conductive plate
thickness is high compared to PP Capacitors making the
electrical stress very low.
2. Normal stress on dielectric PP film is very low.
3. ALL PP Film Capacitors are impregnated with non-toxic
low viscous stabilized impregnant under high vacuum.
This result in inpregnant fluid replacing air-pockets, due to this
capacitors develop very good partial discharge
characteristics. This attributes to voidfree impregnation of capacitors
eventually developing very good partial discharge
characteristics.
4. ALL PC Capacitors have the capability to bear
harmonics and withstand high inrush current owing to
sturdy construction. Impregnated capacitors oil results in excellent heat
dissipation.
5. ALL PC Capacitors have very low losses because of the
absence of paper & consequently they have very low
temperature rise.
6. Power factor of the system remains unaffected for an
appreciable period of time. Highly suitable for
Automatic Power Factor Correction. An excellent selection for Automatic
Power Factor correction.
7. Initial cost is higher compared to MPP Capacitors but
its long life & consistent unchanging performance makes
it cheaper.
