Hi fernandoCFE,
For a sinusoidal current,under steady state conditions the voltage is:
Uout= M*j*ohmega.Ip
The signal is a sinusoidal voltage, proportional to the
current, with 90º phase shift (lead).

hello fb559,
as far as i know the memory buffer overflow issue was sorted out when ver 2.0 was released. The version after 2.0 is 2.5.The ver 3.0 has extra communication protocols compared to 2.5. The technical reference manual (download from www.abb.com/substationautomation) provides more...
hi
Mesh stations are a little bit tricky and can only be found in UK and probably central Saudi Arabia, these days.
The station uses one Switch or CB to control multiple circuits (line/trafo or even banked trafo bays) and has complex control & protection requirements. there are single switch...
hello,
like the others said, there is no bus protection for mesh stations per se. However you will be required to provide mesh corner protection and this is done with a differntial relay + CT supervision (low or high impedance though these days low impedance is preferred) per corner. The...
