Preempts explosion and consequent fire in all type of oil filled of transformer explosion prevention. Patented design and method having patents in more than 80 countries. Environment friendly fool-proof system. Retrofit possible with minimum outage. Suitable for indoor/outdoor/unmanned installations. Can be operated in the absence of power. Low maintenance. Unaffected by climate changes. Approved by all renowned transformer manufacturers, railways, domestic and international utilities, Consultants and Power Producers. The Patented design of Transformer Conservator Isolation Valve (TCIV), now increasingly being used as a standard accessory in oil filled Transformers upto 765kV, isolate the Conservator oil from draining during bushing bursting, Tank rupture and / or fire, avoiding further aggravation by the Conservator oil in the event of fire. ISO 9001:2008 certified. SCADA compatible system suitable for IEC/DNP protocol available on request. More than 3000 systems in operation in over 20 countries in Europe, South America, Central America and southeast Asia. Till date more than 5000MVA of transformers of ratings as large as 315MVA in voltage class upto 400 kV have been saved from explosion and fire under different fault conditions.
