An alloy of tin and lead in the ratio 40:60 is used to make
fuse wire and an alloy of tin and lead in the ratio 60:40 is
used to make solder wire.(solder wire melts easily than fuse
wire since tin is more)
In a 11Kv/433Volt Delt-star step down transformer one one
line(Line-B) of HT site is open & earthed on DP structur.
What will be the voltage on LT side R-Y, Y-B,B-R and R-N, Y-
N & B-N?. Please help to understand the problem with
Arvind , Jaipur.
We have a 12MW power plant & we inject 5-6MW power to
Orissa GRID. For this we have a 33KV/11KV switch yard
having 12.5MVA power transformer. Some times we draw power
during emergency. It is observed that during Export or
Import for load less than 500Kw the power factor is
decreasing to 0.3 . This is happening only during export or
import. During island condition TG power factor OK.Our
capacitor bank is provided with our Power plant auxilliary
load. Please suggest how I can we improve our power factor
during low load (GRID).
