2. Type CIL Fuses - (Indoor) Current Limiting Capacitor Fuse For
Use In Metal - Enclosed Equipment
9
General Description
The Type CIL Fuse is a full range current limiting capacitor fuse. It is
designed for indoor use only. CIL fuses exist in voltage classes of 5.5 kV,
8.3 kV, 15.5 kV and 23kV. The primary application of these fuses is indi-
vidual capacitor unit fusing for metal enclosed equipments. The CIL fuse
is current limiting, indicating and disconnecting.
The Type CIL current limiting capacitor fuse is a two part design:
The high current section interrupts high 60 Hz fault currents and/or high
frequency discharge current from parrallel capacitors.
The low voltage section consists of a standard NEMA type K fuse link
mounted in a fiber tube. The low current section interrupts fault current
association with progressive failure of the capacitor unit DIELECTRIC, or
60Hz fault current limited by the circuit impedance to low values.
This type of design reduces fuse replacement cost to the price of a
NEMA type K fuse link when low current interruption occurs.
The CIL capacitor fuse must be used with an ejector spring. (see page
10). This spring ejects the link’ s leader giving a position indication of a
blown fuse.
Application
Voltage: The CIL fuse is used only for fusing individual single phase
capacitor cans. Therefore, the CIL fuse voltage rating can be determined
from the voltage rating of the capacitor unit - (see Table 1). Do not apply
CIL fuses above their rated voltage.
Energy: The CIL fuse is generally used on those capacitor banks where
parallel energy is more than 20 kilo-joules or 6000 kVAR. The CIL fuse’s
maximum parallel capacitor discharge energy rating is shown in the
Technical Data table.
CIL fuses are to be applied ONLY where there are 2 or more capacitors
in parallel per group and where low inductively limited faults can flow .
See appendix.
Current
Table 1 lists the individual fusing recommendations for applying CIL
fuses in indoor capacitor banks. The fusing tables are based on the fol-
lowing:
Capacitor Current= kVar unit
kV unit
Minimum Fuse Current= Capacitor Current X 1.35 Protective Margin.
The protective margin accounts for normal overvoltages, harmonics,
capacitor tolerances and a 40° C. ambient.
Note: Table 1 current ratings are based on 40° C. ambient style numbers
shown in Table 2. Derated current ratings for 55° C. ambient applications,
are also shown in Table 2.
