General Description Nitrogen injection fire protection system designed for oil fil led transformers, shall prevent tank explosion and the fire during internal faults resulting in an arc where tank explosion will normally take 3-4 seconds after arc generation and also ex tinguish the external oil fires on transformer top cover du to tank explosion and / or xternal failures like bushing fires, OLTC fires and fire from surrounding equipments. It sho uld be fully automatic and shall require minimum mainten ance and practically no running co st. The system shall work on the principle of DRAIN AND STIR and activation, shall drain pre-determined quantity of oil from the tank tope throu gh outlet valve to reduce the tank pressure and inject nitrogen gas at high pressure from the through inlet valves to create stirring action and reduce the temperature of top
