Product Description
Features and Benefits
- It employs a through-type current transformer, which is completely isolated from the secondary circuit, ensuring high safety.
- It adopts a distributed measurement architecture, featuring on-site measurement and digital transmission, with protocol compliance. DL/T860 Standard
- It can be installed live, meaning no power outage is required for installation on the main equipment, enabling convenient and rapid system integration.
- A digital filtering method is employed to eliminate the “zero-drift problem” inherent in analog filters.
- Employing a high-precision active zero-flux sensor, the system intelligently selects the conditioning circuit and amplification factor based on the magnitude of the measured current, thereby significantly enhancing measurement accuracy.
- Features real-time on-site temperature and humidity measurement.
