Insulation Power Factor testing on an oil-filled transformer is not helpful in determining ___

A form of AC testing that applies voltage and measures the leakage/loss current of electrical insulation.
It is a type of insulation testing used to evaluate the integrity of electrical insulation.

Determine maximum permissible load which a 15 MVA, ONAN cooled transformer to IS : 2026 can take for 6 hr, if the initial load on it was 12 MVA. The weighted ambient temperature is 20˚C. Assume the permissible load kVA as a fraction of rated kVA is 1.25.

Maximum permissible load = Rated MVA rating*fraction of rated kVA
Maximum permissible load = 15*1.25
Maximum permissible load = 18.75 MVA

A new generation of smart meters is known as ____

The second generation of smart meters are known as SMETS 2.
Full form of SMET is Smart Metering Equipment Technical Specifications.
It is with the previous generation known as SMETS 1.
SMETS 2 smart meters were introduced in 2018.

A given solar cell has the following specifications:
Open-circuit voltage, Voc: 0.7 V
Short-circuit current, Isc: 3.5 A
Short-circuit current, Isc: 3.5 A
Short-circuit current, Isc: 3.5 A
If the solar cell operates at maximum power point, calculate the efficiency.

Equation is given by:
Efficiency = (F.F*Voc*Isc)/Pin
= (0.6*3.5*0.7)/10
= 0.14702
% efficiency = 14.7 %

In 2019, India stands ___ position in the consumption of electricity in the world.

As per the key statistics data of IEA With electricity consumption reached to 1,164 TWh in the country till November 2019, India ranked third among the top ten electricity consuming countries across the globe.
