Product Description
⚡ Protective Function Identifies fault current automatically; realizes instantaneous current cutoff, time-limited current break, regular flow, directional flow, overvoltage, under-voltage, and single-phase ground protection. Includes cooling load start and inhibition of open circuit.
📊 Measurement Function Measures three-phase current, three-phase voltage, active power, reactive power, active energy, reactive energy, peak/valley electricity, power factor, and frequency.
🎮 Controlling Function Enables on-site operation and remote control. Achieves fault location, automatic fault isolation, and rapid power supply resumption. Realizes automatic load shedding, capacitor cutting, and backup power management.
📡 Communication Function Reports fault and operation information via wireless public networks or specialized networks. Supports various communication protocols and parameter modification via handheld PDA with self-inspection feedback.
💾 Data Record Function Automatically records, saves, and tracks operation and fault data for comprehensive monitoring.
🔄 Synchronous Switching Function Searches for zero-crossing points automatically according to load features. Realizes synchronous switching to effectively restrain over-voltage and inrush phenomena, ideal for capacitors and transformers.
🧠 Intelligence Function Conducts on-line analysis of power network parameters and circuit breaker performance. Cooperates with distribution automation systems for hierarchical remote control management.
👥 Load Management Function Works with intelligent compact solid insulation switch equipment to solve electricity fee issues for scattered or temporary resident customers.
