Answer / tim lafferty

Isolation transformer means that the device has a galvanic
separation between the primary and secondary. Galvanic
isolation means there is “insulation” that does not allow
current flow or no electrons to transfer between two sides
of the circuit. Isolation transformers can be kV or micro
Volt size. They may be 1:1 or 1000:1 or 1:10,000. The
term isolation transformer does not indicate anything about
the transformer except that the secondary is not electrical
connected to the primary. Meaning the primary and
secondary grounds are completely independent of each
other. The connection between the two sides the magnetic
flux not an electrical connection.

As name suggest Isolation transformer does not alter
power,voltage or current level.It only electrically isolate
two parts of circuits.It has turn ratio of 1:1
It is use in amplifier circuit.

i heard that power factor(PF) is the main concern for industries, if they are maintaining PF around 0.6 they will be fined for that. now the question is, how can they improve the PF ranging between 0.9 to 0.95 which is safe for them i,e escaping from the fine?

As we know,charged clouds(from which lightning stroke initiates)may be charged with either +ve charge or -ve charge. Now say one cluster of cloude is fully charged with +ve charge & another cluster is fully charged with -ve charge. In the sky these two cluster of charged clouds have come in such a distance that, if they come clouser by some few yeards then the lightning discharge will take place between these two cluster of clouds. Under such a situation an Aircraft came inbetween. what happend??
