How to calculate capacitor bank value to maintain unity power factor with some suitable example?
What is the difference between PS & metering CT (5p20,0.5 etc.)? Why in PS class CT only Vk is given ? Is PS class CT is more accurate than metering CT?
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?
