Keep your electricity flowing & business growing
Uninterrupted power supply is the goal of every power transmission and distribution company, but many problems lie in the path of achieving it. These problems can lead to unnecessary shutdowns, and can cause huge monetary and man-hour losses. To help power companies achieve highest efficiency, FLIR brings a wide range of thermal imaging cameras and T&M products.
FLIR’s wide range of products for predictive and preventive maintenance
Substation Thermal Image
These products help in detecting hot spots from a safe distance, avoiding unwanted shutdowns, identifying hazardous SF6 gas leakage, monitoring high voltage electrical substations continuously from remote location, etc.

Use the right cable wires, avoid disaster fires Electrical cables play a vital role in the safe delivery of power in an electrical network. Keeping in mind the health & fire safety aspects of cabling, one should pay more attention to the type of cables being installed for different uses. The performance of a fire system depends heavily on the cabling.
Understanding the types of cables and their applications Flame Retardant Cables
Fire Resistant (FR) Cables
Fire Resistant Low Smoke Cables
Low Smoke Zero Halogen Cables
Fire Survival (FS) Cables
Standard Installation conditions
Non - Hazardous Industry
Chemical or Refinery
Theatres, Hospitals, Shopping Malls, Airports etc.
Fire Alarm Systems, Elevators, Fire Fighting Systems, Metro Lighting Systems, Mines etc
Cost of human life is much more than the cost of a cable. Support all cables with a strong backbone of ‘Copper’ to complete the life span.

From the President’s Desk
Dear Friends, It has been a period of hyper activity at IEEMA for last 45 days. It started with annual conference and AGM. “Kal Aaj aur Kalâ€? during annual conference was an event full of insights from some very experienced, knowledgeable and erudite personalities. We also had a landmark “Trafotechâ€? with more than 400 participants and had national and international experts presenting papers on diverse aspects of “Transformer technologyâ€?. While the conference focussed on future of transformers, to close the loop , there was an exhibition where all aspects of history of transformers including published literature was painstakingly complied. Director Operations (PGCIL) and Secretary Power were fascinated and spent substantial time going through the exhibits. IEEMA engaged with Ministry of Power and Ministry of Commerce on Government of India initiative in creating e-market place for all government procurements. We were invited for an interactive session with MoP, MoC, CEO GeM where team IEEMA led Mr RK Chugh, Vice President, IEEMA very effectively communicated sellers’ concerns, enthusiasm and perspective. IEEMA can use this platform to pursue our long standing desire for an pan-India standardised technical and commercial terms. While last six weeks were marked with hyper activity, the pace is unlikely to abate for next six weeks as well. Most notable events ahead are T&D conclave and E3 Exhibition cum Conference. T&D Conclave is now more than a decade old with last version witnessing almost 400 participants and 36 co-hosts has evolved into a unique platform. Friends, the woes that besiege our industry are many. At this conference we meet so many personalities who inspire us to think out of box, innovate and learn how people with more intractable challenges have made things work for them. It has become a look -forward- to-day with an opportunity to unlearn and relearn things and network with stakeholders straddling across product divisions. E3 will showcase, how East is on energisation and empowerment mode. The conference focuses on variety of subjects. Today when the monster of reverse bidding is gnawing away at our vitals, there is need to enhance awareness RI 3ULFH YV 9DOXH SURSRVLWLRQ ZKLFK LV WKH Ă€UVW WKHPH RI WKLV &RQIHUHQFH 7KH two days conference will have three more subjects 1) Electrical Fire Safety 2) Enhancing our Global footprint and 3) future of electricity. Apart from Conference, we shall have a three day exhibition.

and ASEAN Countries have become particularly important in the context of India’s look East policy and recent MoU with Myanmar for operationalising SITTWE post to bolster NE connectivity. No other regional block can match ASEAN in improving the living conditions of such a broad swathe of humanity. The progress in last 50 years since the formation of ASEAN countries and the concomitant peace and prosperity for its more than half a billion inhabitants is a lesson for rest of the world. Last but not the least, Instrument Transformer division is holding the 4th edition of Tech-IT Conference on 13-14 December in Gurgaon. We expect more than 250 delegates attending this conference Let us connect and participate whole heartedly to take this to next level

Dear Members, Energy generation and consumption chain has witnessed very large transformations due to urbanization, industrialization, transportation & lifestyle changes. The increased awareness of the environmental impact and the carbon footprint of all energy sources, including electric power production, have also given impetus to the growth and adopting of renewable as well as alternative energy. The government has pledged to cut its carbon emissions by 33-35% from 2005 levels to 2030. It has also pledged that, by 2030, 40% of the country’s electricity needs would come from non-fossil fuel thus India Inc is gearing up for this big change. With more emphasis on Renewable energy sources like wind, hydro and solar, the need of hour is to have a grid that is highly adaptive. Here Smartgrid comes into the picture. The potential gain of smart grid includes improved reliability and power quality, reduction in peak demand, reduction in transmission congestion FRVWV SRWHQWLDO IRU LQFUHDVHG HQHUJ\ HIÀFLHQF\ HQYLURQPHQWDO EHQHÀWV JDLQHG by increased asset utilization, increased security, ability to accommodate more renewable energy and ease of repair in response to malicious attacks. Another area of focus is Power quality, Micro grids, Industry 4.0, Energy Storage to name a few. Talking about government’s ambitious plan of all vehicles to be electric by 2030. By any measure, India’s electric vehicle (EV) aspirations are steep from where we stand today, but they have sparked remarkable interest and action in policy, industry and research arenas. A push to mandate all vehicles sold by 2030 to be electric seems to have tempered, but high EV penetration scenarios remain likely. While costs and consumer choice remain fundamental factors, there are three additional key issues for realising any growth: (1) manufacturing; (2) grid capabilities; (3) charging infrastructure. Amidst all the new developments, IEEMA members will have to play a big role so that Country’s need can be catered. But the question here is, Are we ready for the new era? Do we have the latest infrastructure for this big change? Are we spending enough on our research and development activities? Do we have skilled and trained manpower to cater to the needs of the industry? And lastly How would the current industry ecosystem change as a result of the HOHFWULÀFDWLRQ GULYH E\ WKH *RYHUQPHQW" We at IEEMA are engaged with membership and the Policy makers to bridge WKH JDSV DQG ÀQG QHZ EXVLQHVV RSSRUWXQLWLHV IRU RXU PHPEHUV LQ WKHVH changing times . It becomes so very important hence, for our members to take advantage of deliberations at IEEMA Product Divisions and various committees to push the interest of industry and that of our country together, to arrive at these new frontiers.

As a result, several byproduct gases like Hydrogen (H2), Methane (CH4), Acetylene (C2H2), Ethane (C2H4) and Ethylene (C2H6) are generated and dissolved into the oil.
