The capacitor protection consists of: Fuses for individual capacitor unit protection; Circuit breakers with fault- and condition-monitoring relaying or circuit breaker for capacitor-bank protection; Fuse for individual capacitor unit protection. The following criteria are applied for the selection of capacitor fuses for individual units and for
While each capacitor unit generally has fuse protection, if a unit fails and its fuse blows, the voltage stress on other units in the same series row increases. Each capacitor unit is designed to withstand up to 110% of its rated voltage. If another unit in the same row fails, the stress on the remaining healthy units increases and can exceed
The capacitors can be designed with internal/external fuse or fuseless. Relays of various designs are available. From the NC020 of the Pro-N smartline series for low-cost applications to the relays of the Pro-N and Pro-N Extended series for large systems for
Fusing per the Code provides reasonable protection if the capacitors are the metallized film self-healing type. If not, each capacitor should be individually fused as shown in Figure 2. Fusing
To mitigate this, I am planning to make two changes - (a) Use a branded capacitor like panasonic or so and (b) Use some sort of surge protection circuit as shown below: This is an inexpensive circuit that I could come up with -

Capacitor Bank Protection and Control REV615 Capacitor bank protection and control in medium voltage networks The relay is intended for protection, control, measurement and supervision of single Y, double Y and H-bridge connected capacitor banks used for compensation of reactive power in utility and industrial power distribution systems.
The fuse, by its design, avoids absorbing all of the available energy on the series group. This fuse is used for capacitor banks with a large number of parallel capacitors. It can be used on applications with essentially infinite parallel stored energy, as long as sufficient back voltage can be developed to force the current to extinguish.
Most capacitor fuses have a maximum power frequency fault current that they can interrupt. These currents may be different for inductive and capacitively limited faults. For ungrounded or multi-series group banks, the faults are capacitive limited.
Eaton's Cooper PowerE series bus-mounted expulsion-type capacitor fuse provides highly reliable, economical protection for capacitor banks where medium-energy-interrupting ability is required. See Table 1 for electrical ratings. The fuse tube is constructed of bone-grade fibre overwrapped with epoxy-bonded filament-wound fiberglass.
Capacitor bank protection products and systems provide complete primary and backup protection for all types of capacitor configurations. This relay protects grounded and ungrounded, single- and double-wye capacitor configurations and allows you to obtain full control of your capacitor banks.
For high voltage capacitor fuses, this is generally defined as 8.3, 15.5 or 23 kV, the distribution system maximum voltages. Other voltage ratings may be available for special applications. When a capacitor fails, the energy stored in its series group of capacitors is available to dump into the combination of the failed capacitor and fuse.
This relay protects grounded and ungrounded, single- and double-wye capacitor configurations and allows you to obtain full control of your capacitor banks. Combining these components with capacitor bank protection devices expands their functionality.
