i have dry type transformers can you help me that how many
tests i can do to know the performence of transformer and
also please tell me about the BDV test and Insulation
resistance test in oil cooled transformers
in our all power plant have connected in grid and grid
voltage and plant voltage is same, but as per as electrical
concept the power will transmit from high potential to low
potential but here altough same,then how power transmit
from power plant to grid.

As we use capacitor bank in 3ph ckt to improve PF,
can we use capacitor in single ph domestric use,
in house we have Fan,Mixer,electric cooker,iron,tube choke
they also lag the system,because it is inductive load.
if it is possible to improve PF of single ph system--
if yes- type of capacitor to be used,connection diagram,
working in detail.
if no-- list it.
