Three/Single Phase Programmable RLC Load

The Programmable Three-Phase/Single Phase RLC Load System is a hardware-based programmable load bank that uses real resistors, inductors, and capacitors to simulate a wide range of electrical loading scenarios. Controlled via a LabVIEW-based graphical user interface (GUI), the system allows users to independently set resistive (R), inductive (L), and capacitive (C) load levels by entering reference power values, offering precise and dynamic control of active and reactive loads. With built-in power measurement, harmonic analysis, and multi-point communication this platform is ideal for power systems education, energy audits, and three-phase power quality research.
