Answer / priyanka

high vtgs are produced by high vtg surges,a sudden
increase of voltage damages the equipment throughout t/m
line so surge absorbers have to be used to protect the
equipment as it is very costly.

Answer / yaswanth

high voltages are can also produced either electerically or
electronically.it is used to test the equipment's critical
voltage.ex.Insulation measuring, t/f oil testing.

Answer / chandrasekar

impulse generator can be used produce very high voltage for
short duration. And this high voltage is produced to test
electrical equipments like transformer , lightning arrrestor etc

Answer / alok

High voltages are
produced as a result
of various unwanted
factors like harmonics,
and these have to be
rectified from the
system, either they
may cause temporary
or parmanent damages.

I need to compare the energy consumption of an industrial machine before and after improving. Shall I compare the apparent power or the active power? I know usually factories use compensated capacitors (or other similar components) to compensate the reactive power, so if I use the apparent power, it's not the real power consumed.
