ate and thus bringing the temperature of top oil layer down. Transforme conservator isolation valve blocks the flow of oil from conservator tank in cas of tank rupture / explosion bushing bursting. Nitrogen occupies the space created by oil drained out and acts as an insulating layer over oil in the tank nd thus preventing aggravation of ire. The system shall be provided with automatic controls for fire revention and fire extinction and besides remote lectrical push button control on control box and local manual control in the fir -extinguishing cubicle shall be provided. 5.9 System Activating Signals ) To avoid transformer explosio two fast trip signals given circuit breaker of transformer and Buchholz relay paralleled with pressure relief valve/ pressure and temperature sensors to initiate: . Explosion prevention by opening quick depressurization valve release the internal pressure and to prevent the transformer explosion. 1 of 1 INDRADHANUSH GAS GRID LIMITED TECHNICAL SPECIFICATION FOR NATURAL GAS COMPRESSOR STATION FOR NORTH EAST GAS GRID PIPELINE PROJECT ______________________________________________________________________________________________ TS NO.: MEC//2UU/0/2/0 Electrical system Chapter-0.0 2, MECON Limited, All Right Reserved Pag 6 of 2 ii. Oil cooling by inje cting large flow nitrogen at the transformer base to limit the damages of overheated parts affected by short circuit and to evacuate the very explosive hydrogen gas by dielectric oil. ) . The fire protection back up system should be initiated by signals from one of the high temperature sensors, located on th transformer cover and by the operation of Buchholz relay parall eled with pressure relief device/ pre ssure and temperature sensors. The drain valve should open out with in 3 second. The nitrogen inje ction shall cause stirring of transformer oil and should immediat
