摘要
The present invention relates to an apparatus for determining electrical power supplied by an electrical power supply system comprising a plurality of phases and using shunt resistors. Furthermore, the present invention relates to a method of testing or calibrating such an apparatus or a plurality of such apparatus simultaneously. The present invention provides an apparatus for determination of electrical power and using shunt resistors where testing or calibration of current sensing means (shunt resistor) and voltage sensing means (electrical circuit) can be carried out independently of each other.
