Product Description
Features and Benefits
◆ Low-frequency zero-crossing carrier, strong anti-interference performance, transmission distance > 3 km.
◆ Suitable for various complex environments (such as adjacent transformers sharing high voltage, common grounding, or shared cable trenches), with no crosstalk.
◆ Full coverage of low-voltage distribution areas, with identification time under 6 seconds and 100% accuracy.
◆ Zero-sequence pulse current detection: a single host can simultaneously monitor 12 branch circuits.
◆ It adopts a master–extension configuration, allowing for multiple masters and extensions to be used in combination, thereby enhancing operational efficiency.
◆The host unit features measurement of voltage and current, vector diagram display, phase sequence identification, and harmonic analysis up to the 21st order.
◆The instrument is equipped with multiple protection features, including overvoltage and overcurrent safeguards, to ensure safety.
