3-phase, 3-wire (STE-B-4T) system and 3-phase 4-wire (STE-C-4T) systems with balance and unbalanced load. They are suitable for measurement of both import and export of power. The output is a load independent DC current or voltage which is proportional to input power. The output can be connected directly to indicating instruments or to data transmission system.
