A power quality tester
By introducing a three-phase test interface, a switching selection module, and a multi-dimensional test circuit array, combined with a controllable power supply, active power quality testing is achieved. This overcomes the limitations of traditional testers in identifying common-mode errors and complex problems, and improves the depth and accuracy of power quality diagnosis.

AI Technical Summary
Traditional power quality testers struggle to effectively identify and quantify common-mode errors and complex power quality issues, and are unable to deeply reveal the dynamic response and interactions of power systems, resulting in limited diagnostic depth and predictive capabilities.
Employing at least two three-phase test interfaces, a switching selection module, a test circuit array, and a controllable power supply, active and multi-dimensional power quality testing is achieved through mimicry load, out-of-order testing, deviation testing, and condition simulation circuits. These circuits include mimicry load test circuits, out-of-order test circuits, deviation test circuits, and condition simulation test circuits, combined with electronic loads and controllable power supplies, to perform dynamic interaction and disturbance simulation.
It significantly improves the depth, breadth, and accuracy of power quality diagnosis, enabling proactive identification and quantification of complex power quality problems, providing in-depth diagnostic information, and enhancing fault diagnosis and optimization capabilities.
