Hello R.Shafiri. To my knowledge thereare no PLCs that offer a module capable of measuring Real (apparent) Power directly. For that you need to have in your 10 kV system a powermeter(associated with CTs and PTs properly installed in the electrical system you want to monitor) capable of measuring Volts, Amps andthe power factor, capable of multiplying the three values (to obtain the Real Power), and capable of transfering this value over a network or analog medium, such as your PLC is capable of reading it. See the following links for some basic information on the subject: http://en.wikipedia.org/wiki/Active_power#Real.2C_reactive.2C_and_apparent_powers |
