A traditional protection implementation relies on several devices rather than just one—for example, a transient voltage suppressor (TVS) for overvoltage protection, an in-line fuse for overcurrent protection, a series diode for reverse battery/supply protection, and a mix of capacitors and inductors to filter out lower energy spikes.
Various devices act as the "fire extinguishers" amongst electronic components, providing protection against excessive and potentially dangerous or damaging currents, voltages or temperatures. Some are single-use and must be replaced when blown but others are self-resetting or user-resettable.
In these scenarios, a specialized device can be used to gain a significant cost advantage over traditional TVS diodes and varistors: the ESD-safe multi-layer ceramic capacitor (MLCC). These capacitors contain specialized

Shunt capacitor banks, also called filter banks, are widely used in transmission and distribution networks to produce reactive power support. ABB's capacitor bank protection is used to protect against faults that are due to imposed external or internal conditions in the shunt capacitor banks.
For Delta banks, a similar principle can be adopted using an “H” configuration of capacitors on each phase. For single Wye-grounded neutral capacitor banks, the most straight-forward protective control is neutral-current-type relaying.
