| Description | TRANSFORMER PROTECTOR (TP) | Water Sprinklers or HVWSS | CO2 Fire Extinguishing System |
|---|---|---|---|
| Functionality | Explosion and Fire Prevention System | Fire Extinguishing System. | Fire Extinguishing System |
| Activation | - Activates with First Dynamic Pressure Peak avoiding static pressure to build up. Hence, no transformer explosion. - Activates under both prevention and extinguishing mode. | - Activates when explosion has already occurred; - Activates under extinguishing mode with less efficiency. | -Activates when explosion has already occurred and fire has taken place. -Activates under extinguishing mode with less efficiency. |
| Transformer tank status | Tank never ruptures | Tank rupture because of explosion | Tank rupture because of explosion |
| Probability of damage cause to surrounding equipments | Zero (0). No Damage to surrounding equipments as there is no explosion. | High probability of damage to surrounding equipments as transformer explodes. | High probability of damage to surrounding equipments as transformer explodes. |
| Breakdown time | Limited; Transformer get back to service after the repair of the fault. | High; As transformer need to be replaced. | High; As transformer need to be replaced. |
| Maintenance cost | Very Low | High, Nozzle blockage etc… | High, Nozzle blockage etc. refilling after expiry i.e. one year. |
| Additional cost | Not applicable | Water need to store permanently, Maintenance of the water tank | Co2 needs to be stored in Co2 fire extinguisher cylinder and its leakage needs maintenance and repair/replacement of cylinder. |
| Adaptability & space utilization | Can be easily adapted with existing as well as new transformers. Designed is optimized as occupy less space. | Piping’s are routed around the transformer making whole set up complex. | Piping/Hose Pipes around the transformer making whole set up completely hence becomes useless during incident. |
| Efficiency during incident | Activates within milliseconds and prevent explosion. So, there is no explosion and fire. | Piping of water sprinkler itself explodes with transformer explosion. Hence, useless during incident. | Piping of Co2/Hose pipe itself explodes with Transformer explosion, hence becomes useless during incident. |
| Oil Spill | No oil spill | Oil spill with transformer explosion resulting in environment pollution. | Oil spill with transformer explosion resulting in environment pollution. |
