1910.304 - Wiring design and protection.
To enhance the protection, a Zener diode can be used instead of a standard diode to also protect the cell against the over-voltage condition. LTC3625 features reverse-voltage protection as default. The protection function should also be able to monitor and detect excessive supercapacitor leakage currents.
Electrolytic Capacitor Failure Detection. Electrolytic capacitors are the most common source of malfunction/weird behavior of electronic devices, especially in the power supply part. Follow this procedure to spot a bad electrolytic capacitor: Visual Inspection: look for the explosion, bulgy signs, or leakage of the chemicals. Without any ...

1.2 REFERENCED STANDARDS American National Standards Institute 11 West 42nd Street New York, N.Y. 10036 ANSI/IEEE 18-1992 Standard for Shunt Power Capacitors ANSI/IEEE 100-1992 Dictionary of Electrical and Electronic Terms ANSI/IEEE 1036-1992 Guide for Application of Shunt Power Capacitors
The short circuit protection of the capacitors is provided by the switch disconnectors. For the capacitors the fuse link rated current should be 1.6 time of the rated reactive current of the capacitor. I n =Q / (U n ×√3) where: U n – rated voltage of the mains, Q – rated power of the capacitor at rated mains voltage.

Also in this case the fuse should meet the requirements described in the general standard IEC 60282-1 [2], with additional tests resulting from this standard. The summary of the analyzed standardization documents is shown in diagram 2.1. — Fig. 2.1. European standards covering the topic of
