MGVCL Exam Paper (30-07-2021 Shift 3) The sites where the capacity factor is ____ are not considered suitable for wind power generation. less than 24% greater than 12% less than 12% greater than 24% less than 24% greater than 12% less than 12% greater than 24% ANSWER EXPLANATION DOWNLOAD EXAMIANS APP The capacity factor is the ratio of an actual electrical energy output over a given period of time to the maximum possible electrical energy output over that period.Nuclear power plants are at the high end of the range of capacity factors
MGVCL Exam Paper (30-07-2021 Shift 3) A 1000 kVA ONAN cooled transformer has a load of 500 kVA throughout the day except for a period of 2 hours. What is the permissible overload for a duration of two hours. Assume the permissible load kVA as a fraction of rated kVA is 1.43. 700 kVA 1430 kVA 1050 kVA 715 kVA 700 kVA 1430 kVA 1050 kVA 715 kVA ANSWER EXPLANATION DOWNLOAD EXAMIANS APP Permissible overload for transformer = Full load kVA*factor for permissible overload= 1000*1.43= 1430 kVA

MGVCL Exam Paper (30-07-2021 Shift 3) A conductor having surface density is embedded in a dielectric medium of permittivity. The electric field in the medium is E. If it is known that the pressure p on the conductor surface is equal to the electric energy density in the medium, then p (in SI unit)is given by σ²/(2ε) σ²/(4π) σ/(4πε) σ²/(2πε) σ²/(2ε) σ²/(4π) σ/(4πε) σ²/(2πε) ANSWER EXPLANATION DOWNLOAD EXAMIANS APP As the point is near to the conductor will act as infinite sheetElectric field (E) is given by:E = σ²/(2ϵ)
