What is the normal value of delta in rotor angle stability
or transient stability?
Why it selected so?
Answer / iamdon
The normal value of delta(load/power/torque angle) is 30
degree.
This is selected so because during power swing (in case of
instability) the flactuation of delta is in the range of +/-
30 degree.This will result the range of delta in 0-60
degree.In this region(0-60)sine curve is linear.

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.
