Bombay Stock Exchange
BSE Limited, also known as the Bombay Stock Exchange (BSE), is an Indian stock exchange. It is located on Dalal Street in Mumbai. Established in 1875 by cotton merchant Premchand Roychand, a Jain businessman, it is the oldest stock exchange in Asia, and also the tenth oldest in the world. The BSE is the 8th largest stock exchange with an overall market capitalisation in the world with more than ₹276.713 lakh crore, as of January 2022. Unlike countries like the United States where nearly 70% of the country's GDP is derived from large companies in the corporate sector like Apple and Tesla, the corporate sector in India accounts for only 12–14% of the national GDP (as of October 2016). Of these only 7,400 companies are listed of which only 4000 trade on the stock exchanges at BSE and NSE. Hence the stocks trading at the BSE and NSE account for only around 4% of the Indian economy, which derives most of its income-related activity from the unorganized sector and household spe ...

Chandrapur Back-to-back HVDC Converter Station
The Chandrapur back-to-back HVDC station is a back-to-back HVDC connection between the western and southern regions in India, located close to the city of Chandrapur. Its main purpose is to export power from the Chandrapur Super Thermal Power Station to the southern region of the Indian national power grid. It is owned by Power Grid Corporation of India. The converter station consists of two independent poles, each with a nominal power transmission rating of 500 MW. Both poles were built by GEC-Alstom between 1993 and 1997 and have nominal DC voltage and current ratings of 205 kV, 2475 A. The converter station is located from the eastern terminal of the Chandrapur–Padghe HVDC transmission system. The close proximity of the two converter stations meant that the control systems needed to be carefully coordinated, a task made more challenging by the fact that the two stations were built by different manufacturers. To address this problem a series of joint simulatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Megawatt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units, International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Energy transformation, energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish people, Scottish invention, inventor, mechanical engineer, and chemist who improved the Newcomen steam engine, Newcomen engine with his own Watt steam engine, steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one Newton (unit), newton, the rate at which Work (physics), work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potentia ...

Volt Ampere
A volt-ampere ( SI symbol: V⋅A or V A, simplified as VA) is the unit for the apparent power in an electrical circuit. The apparent power equals the product of root mean square voltage (in volts) and root mean square current (in amperes). Volt-amperes are usually used for analyzing alternating current (AC) circuits. In direct current (DC) circuits, this product is equal to the real power, in watts. The volt-ampere is dimensionally equivalent to the watt: in SI units, 1 V⋅A = 1 W). VA rating is most used for generators and transformers (and other power handling equipment) where loads may be reactive (inductive or capacitive). Formulation For a simple electrical circuit running on direct current, the electrical current and voltage are constant. In that case, the real power (''P'', measured in watts) is the product of the electrical current (''I'', measured in amperes) and the voltage from one side of the circuit to the other (''V'', measured in volts) ...
