Final answer:
Protective devices that might be found on a capacitor bank include fuses, overvoltage protection devices, thermal switches, and pressure relief valves.
Step-by-step explanation:
Protective devices that might be found on a capacitor bank include:
- Fuses: These are used to protect the capacitors from excessive current and prevent them from getting damaged.
- Overvoltage protection devices: These devices protect the capacitors from voltage spikes and ensure they operate within their specified limits.
- Thermal switches: These switches monitor the temperature of the capacitors and disconnect them from the circuit if they overheat, preventing thermal damage.
- Pressure relief valves: These valves release excess pressure that may build up inside the capacitors, preventing them from exploding due to excessive pressure.
