Description
Summary:This paper presents several solutions for the application of eco-efficient instrument transformers developed to help better protect our environment. Typical oil-filled and SF6 Instrument transformer products are perceived as not environment friendly and using green-house gas. An alternative solution is to replace mineral oil with BIOTEMP®, a biodegradable fluid as insulating and cooling media without significant cost increase. Meanwhile work on implementation of best practice on compact SF6 Instrument transformer design to lower its impact to environment and reduce SF6 footprint. The latest Fiber-optical Current Sensor (FOCS) integrated with Disconnect Circuit Breaker (DCB) provide not only a substation footprint reduction over 50% but also an environmental friendly design and improved operation safety for its explosion proof. Continuously developing various solutions and product will still be our focus and investment for smart grid substations to increase reliability and lower environment impact.
