IS 13340 : 1993 Power Capacitors of Self-healing Type for AC Power Systems having Rated Voltage up to 650 V - Specification

UDC 621.319.4.027.465                                        ETD29

Reaffirmed 2018

1 Scope

1.1 This standard applies to self-healing capacitor units and banks intended to be used, in particular, for power factor correction of ac power systems of upto and including 650 V rated voltage and frequency 15 to 60 Hz.

Note - Additional requirements for capacitors protected by internal fuses, as well as requirements for the internal fuses, are given in IS 12672 : 1989.

1.2 This are excluded from the scope of this standard:

a) Shunt capacitors of non-self healing type for ac power systems having rated voltage of tip to 650 V;

b) Shunt capacitors for ac power systems having a rated voltage above 650 V; (under preparation)

c) Capacitors for induction heat-generating plants, operating at frequencies between 40 and 24000 Hz;

d) Series capacitors (IS 9835 : 1981);

e) Capacitors for motor applications and the like (IS 1709 : 1984 and IS 2993 : 1975);

f) Coupling capacitors and capacitor dividers (IS 9348 : 1979);

g) Capacitors to be used in power electronic circuits (IS 13648 : 1993);

h) Small ac capacitors to be used for fluorescent and discharge lamps (IS 1569 : 1976);

j) Capacitors for suppression of radio interference (IS 3723);

k) Capacitors intended to be used in various types of electrical equipment and thus considered as components;

m) Capacitors intended for use with dc voltage superimposed on ac voltage.

1.3 Accessories such as insulators, switches, instrument transformers, fuses, etc, shall be in accordance with the relevant Indian Standards.
