Fast-acting vacuum circuit breaker


During a short-circuit fault: the fast‑acting vacuum circuit breaker rapidly discharges the energy stored in its energy‑storage capacitor, and the electromagnetic repulsive force generated by eddy currents directly drives the breaker to achieve rapid opening. It can detect a short-circuit fault within 2 ms and complete opening within 4 ms after receiving the command, enabling it to interrupt the fault during the initial phase of the short‑circuit current, thereby preventing overreaching tripping of upstream switches. The trip‑current threshold is customizable. In the absence of a fault: the fast‑acting vacuum circuit breaker is fully compatible with conventional medium‑voltage circuit breakers in terms of operating procedures, physical dimensions, and wiring configurations. It can detect a short-circuit fault within 2 ms and complete opening within 4 ms after receiving the command, allowing it to interrupt the fault during the first peak of the short‑circuit current and preventing overreaching tripping of upstream switches. The trip‑current threshold is also configurable.

KOGD output reactor


Output AC reactor: Used for smoothing and filtering, reducing transient voltage dv/dt, extending motor life, lowering motor noise, minimizing eddy current losses, decreasing leakage currents caused by output higher-order harmonics, and protecting the power switching devices inside the inverter.

Power Quality Online Monitoring Device


The PM600 (S/M/Q) online power quality monitoring device is specifically designed for monitoring the power quality of “Class I loads.” The MP600 (S/M/Q) features high accuracy, excellent stability, a compact footprint, and easy installation, with accuracy fully compliant with the IEC 61000‑4‑30 Class A standard.

Four-quadrant reactive power compensation controller for photovoltaic systems


The MCGD‑G can monitor reactive power and voltage fluctuations in the grid in real time. By adjusting the reactive power output of the photovoltaic system, it achieves reactive power compensation, thereby enhancing grid stability and power quality. At the same time, it intelligently regulates the active power output of the photovoltaic system based on solar irradiance conditions and grid demand, enabling maximum power point tracking and optimized energy utilization.

APFGD Active Filter Cabinet


The APFGD/SVGGD device is a novel power electronic apparatus designed to address power quality issues, employing an external current transformer to continuously monitor the load current in the power grid.

Wall-Mounted Active Power Filter Compensation Module


The active filtering compensation module is a modular product specially developed by Guangda Electric for dynamic harmonic mitigation in 0.4 kV power supply systems. Connected in parallel with the grid, it uses an external current transformer to continuously monitor the load current. Leveraging DSP, FPGA, and CPLD chips, along with cutting-edge rapid harmonic mitigation and reactive power extraction technologies, it swiftly analyzes the harmonic and reactive components of the load current. Based on user-defined setpoints, it generates PWM pulses to drive a bidirectional converter composed of three-level IGBT modules, thereby producing compensation currents that meet grid requirements. This enables precise, real-time compensation of harmonic and reactive currents, ultimately enhancing power quality. Active modular power quality products comprise three categories: static var generators (SVG), three-phase unbalance compensators (ASVG), and active filters (APF).
