In FDLF method,
B' corresponds to susceptance of unknown of PQ and PV bus
Order of B' matrix is = (n -1)*(n - 1)
Where n is total no. of buses.
Order of B'' = (n - m - 1)*(n - m - 1)
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.
For M no. of series configuration of solar cell,
Open circuit voltage of PV module= M*Voc
= 14 V
Short circuit current of PV module = M*Isc
= 80 A
There is one IEC guideline, number is IEC 599,
Statement of guideline is that "If the ratio of carbon dioxide and Carbon monoxide in Dissolve gas analysis test result is more than 11, it is predict that the condition of paper insulation inside the transformer is poor."
For healthy condition this ratio will be between 4 to 11.
