Luminous Power Technologies was founded in 1988 by engineering graduate Rakesh Malhotra. Luminous was seeded with 4 people in 600 sq ft space in South Delhi. [3] [4] In 2011, French company Schneider Electric acquired a 74% stake of Luminous Power. [5] [6]
A power inverter, inverter, or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). [1] The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC. [2]
Luminous energy per unit time Luminous intensity: I v: candela (= lumen per steradian) cd (= lm/sr) J: Luminous flux per unit solid angle: Luminance: L v: candela per square metre: cd/m 2 (= lm/(sr⋅m 2)) L −2 ⋅J: Luminous flux per unit solid angle per unit projected source area. The candela per square metre is sometimes called the nit ...
Internal view of a solar inverter. Note the many large capacitors (blue cylinders), used to buffer the double line frequency ripple arising due to single-phase ac system.. A solar inverter or photovoltaic (PV) inverter is a type of power inverter which converts the variable direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be ...
Electricity generation in Nigeria began in Lagos in 1886 with the use of generators to provide 60 kW. [10] In 1923, tin miners installed a 2 MW plant on the Kwali River; six years later, the Nigerian Electricity Supply Company, a private firm, was established near Jos to manage a hydroelectric plant at Kura to power the mining industry.
The candela per square metre (symbol: cd/m 2) is the unit of luminance in the International System of Units (SI). The unit is based on the candela , the SI unit of luminous intensity , and the square metre , the SI unit of area .
cd/m 2 (= lm/(sr⋅m 2)) L −2 ⋅J: Luminous flux per unit solid angle per unit projected source area. The candela per square metre is sometimes called the nit. Illuminance: E v: lux (= lumen per square metre) lx (= lm/m 2) L −2 ⋅J: Luminous flux incident on a surface Luminous exitance, luminous emittance M v: lumen per square metre lm/m ...
Nigeria's inflation rate rose to 15.63 per cent in December 2021 compared to 15.40 per cent in November, the National Bureau of Statistics announced on January 17, 2022. The statistics office said the prices of goods and services, measured by the Consumer Price Index, increased by 15.63 per cent in December 2021 when compared to December 2020.
