<p>PURPOSE: A single-phase control circuit of a three-phase power is provided to prevent phase voltage imbalance due to load concentration by monitoring the three-phase and single-phase power through a network controller. CONSTITUTION: A three-phase four-wire power terminal block(10) supplies three phase and single phase power. A three-phase load(20) and a single-phase load(30) are connected to the three-phase four-wire power terminal block. A system controller(40) controls the driving of the three-phase load and single-phase load by detecting the three-phase and single-phase power. A network controller(50) monitors the three-phase and single-phase through network communication with the system controller.</p> |
