    Product Features:

    ► As long as the wiring phase sequence is correct, no parameter settings are required—intelligent compensation control is enabled.

    ► Controlled physical quantity: reactive power + Target power factor, avoiding compensation dead zones and preventing switching oscillations.

    ► Automatic phase sequence identification: secondary wiring terminals of the current transformer S1 and S2 Interchangeable; voltage wire L2 and L3 They can also be interchanged. Once the phase sequence controller is powered on, it will automatically correct any wiring errors; alternatively, you can use the controller’s operation buttons to make corrections manually.

    ► The display offers a wide range of functions, showing four-quadrant power, various electrical parameters, waveforms, harmonic bar graphs, temperature, operating hours, monthly average power factor, and more.

    ► The protection functions are comprehensive, including overvoltage, undervoltage, voltage harmonic exceedance, temperature overlimit, low-load alarm, and insufficient compensation capacity alarm, among others.

    ► Superior anti-interference capability, EMC Electromagnetic Compatibility Testing: EFT Group pulse interference resistance reaches 4000V of the A Level ( IEC (The highest level of the standard.)

Fast-acting vacuum circuit breaker

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 actuates the breaker to achieve rapid opening. It can detect a short-circuit fault within 2 ms and complete opening within 4 ms of 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 of 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.

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 dynamic, precise compensation of harmonic and reactive currents, ultimately enhancing power quality. Active modular power quality products comprise three types of modules: Static Var Generators (SVG), Three-Phase Unbalance Controllers (ASVG), and Active Power Filters (APF).
