Baldev Raj Narang, in this technical article, explains the various types of low-tension (LT) capacitors.The three types of LT power capacitors have their distinctive features. The purpose of this article is to present a clear technical comparison of the different types to enable users to make an informed selection, after taking into account the superiority or otherwise of various performance parameters of the three types. Oil filled MPP (metalized polypropylene) construction is not discussed because it is very uncommon. Oil causes erosion of zinc layer over a period of time due to chemical reaction, thus most of the manufacturers employ resin-filled MPP construction.
Venkat Garimala, Vice President-S&A, CTM, EE, A2E and CSR , Schneider Electric India, in this article, explains that India will need a large pool of skilled manpower in the coming years, and why creating a a healthy talent pipeline is the prime responsibility of the corporate sector.

The biggest challenge for India is to ensure efficient transfer of bulk electricity over long distances maintaining the safety and reliability of national grid. As of now, major portion of the electricity in India is generated in alternating current (AC) form. However, there are technical and commercial hiccups in ferrying AC over long distances. That’s why AC is converted to direct current (DC) in converter stations and transmitted through the high voltage networks. Electricity is again converted to AC before supplying to consumers. High voltage transmission of power reduces the transmission losses.

Our youth are our nation’s critical asset. They represent the future that a nation is building for itself. The young are the storehouse of aspirations, unbridled enthusiasm, raw energy and the passion to achieve goals, big or small. It is therefore important that the youth are provided a robust platform in terms of quality education, skill development and career opportunities so that their combined vision and efforts take the nation forward.
The switchgear industry is among the major industries serving the Indian power sector. In coming days the switchgear industry is expected to show healthy growth. The requirement of power in the upcoming industries and the massive rural electrification drive is poised to keep the switchgear industry very busy. In this industry, technology is the basic resource. It is very natural that most of the multinational companies are major players in the switchgear industry has they have access to source technology. However, in the years to come, many Indian companies are expected to upgrade their technologies and develop switchgear products to serve the rapidly-growing power industry.
When we talk of a scientific mind in the AC electricity supply system, one cannot but admire the Siberian-American inventor Nikola Tesla. What drove him was the following context from where he came: “The desire that guides me in all I do is the desire to harness the forces of nature to the service of mankind.”
By 2020, India plans to install 50 million smart electric meters and is estimated to invest $449 billion in developing smart grid technologies over a period of 10 years starting from 2017. With the country’s demand for electricity growing rapidly, India’s power sector is undergoing a massive transformation. In the next five to six years, India hopes to have a smart meter at every home. An increase in the usage of technologies such as Internet of Things and Cloud-based services are fuelling the government plans to build 100 smart cities across the country.
The most critical element for any successful smart city is the choice of technology for the communication network. So what are the challenges in creating that network? Before we delve deeper into the subject, it is essential to understand a few key things.
All eyes are on India. All roads lead to Rome India! The big question – are we ready?
We have a fairly stable Government, mostly efficient people at the helm, but do we have the will to win, the priority for progress and the ambition to be the best?
If Singapore could do it, Delhi Metro could do it, why not India as a whole? If I were in charge, what would I do? A 5S model emerged in my mind, true to being a cleaning up act indeed!
1) Swaach Industrial Infrastructure: To start any initiative, we need the basic essentials in place of electricity, water, roads, transportation and so on. Peenya in Bangalore has the dubious distinction of being Asia’s largest industrial area. But contrast the amenities here to that in Singapore, and the difference in Government intent shows so starkly and we need to do something about this…quickly, swiftly and efficiently!
Gone are the days when for the buyers seeking respite from frequent power cuts, electricity-based UPS/inverter systems were the only options available in the market. After the advent of solar energy, the scenario has completely changed and the power backup systems studded with solar batteries are all set to take rapid strides across the country in the coming years, if not immediately. It is due to strenuous efforts made by the industry leaders and innovators in this particular segment, India has gradually started moving up the ladder of growth and innovations in solar power generation and its various applications. In line with the target to achieve 100 GW solar power by 2022 set by the government and Jawaharlal Nehru National Solar Mission (JNNSM) for renewable energy, the generic inverter and UPS business has also acquired a new dimension.
However, currently, manufacturing solar batteries is capital intensive and moreover, competition among the suppliers is also rising. Despite the fact that the sun offers plentiful, pollution free and reliable power, the expensive cost of equipment and technology has made it an underutilized energy resource. Typically the batteries used in home energy storage are made with lead acid, or lithium ion chemical compositions. Among all these, the lithium ion batteries are currently considered as the best option for a solar panel system, though lead acid version can be more affordable.
