		abstract={Forward reverse circuit with a three-phase asynchronous motor load at the Electrical
Power Distribution and Utilization Laboratory of the PLN Institute of Technology which
can only adjust the direction of rotation with a constant speed level. One way to be able
to adjust the rotation direction and speed level of a three-phase asynchronous motor is
to use a Variable Speed Drive (VSD). Variable speed drive is an electrical component
that is used to regulate the forward and reverse two-way rotation and adjust the speed
level by controlling the input frequency of a three-phase asynchronous motor. The
research methodology used is a comparative method by simulating two control circuit
conditions and forward reverse power without a variable speed drive and based on a
variable speed drive. The final result obtained is the comparison of electrical energy
usage for 1 hour (60 minutes) on a star-connected three-phase asynchronous motor using
a variable speed drive, which is lower with a value of 0.134 kWh compared to without
using a variable speed drive, which is 0.231 kWh. So that obtained electrical energy
savings of 42% or 0.097 kWh.}
