A three-phase power meter can monitor power on both 3-wire and 4-wire power lines. The power meter measures at least two voltages between phase conductors of the power line, and at least one voltage between a phase conductor and a neutral conductor of the power line when the neutral ...
Power supply circuit for a three-phase induction motor The invention proposes that a supply transformer (T) has primary and secondary windings brought out so that on the primary side a switch (S3) and on the secondary side (S4) can connect them in star or delta. A switch (S1) can conne...

for study of transient stability of power systems in the range of seconds to minutes, the tap transfer process is not modelled and an instantaneous tap transfer is assumed. A detailed delta-hexagonal phase-shifting transformer model is provided in theDelta-Hexagonal Phase Shifting Tr...
Star-Delta Starting Star-delta starting reduces the inrush current by initially connecting the motor windings in a star configuration, then switching to a delta configuration for normal operation. This method is commonly used for motors with higher power ratings. ...
