sigal phase supply is 230 v ac two phase supply is 415 v ac
then why three phase supply having supply is 415 v ac why
not 690v ac
Answer Posted / neeraj pandey
voltage value is the Line to Line Voltage. Line to line
voltage is the voltage between any two phase lines.
In single phase there is one phase and another is earth wire
and voltage between them is 230V approx.
In two phase the line voltage is 1.732 times of the single
phase voltage and the value is 415 V approx.
In three phase system the value of voltage between two
phases are taken which is same as two phase system.
if we take the voltage diff between all three phases it will
be ZERO..

y we use neutral,all r told its used to for closed path..k its a just used to closed path,in a transmission line y we put same conductor used n both phase and neutral..if we use less than phase conductor in neutral mean we ll reduce cost its right r wrong..if we use mean any problem occur in transmission line..
In Power Line Communication (PLC) the wave trap is used to block communication signals from entering neighboring lines. My question is this: Why do they allow for different filtering arrangements on these wave traps? Isn't it always going to be a low pass filter since we want the power frequency to go through, and the comm signal blocked?
please explain to me how to calculate current,voltage,resistance with formula??
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.
