1. Key models
CG2030B, CG2032B, CG2034C, CG2035, etc.
2. Product overview
The CG2035 series product short and grounded fault indicator is an intelligent power fault monitoring device designed specifically for urban and rural power grid ring distribution systems. It can quickly identify short and grounded faults and accurately locate them, greatly reducing troubleshooting time and ensuring safe and stable operation of the power grid.
3. Functions & features
· Fault and temperature detection and indication
It adopts advanced detection algorithms and sensor technology to ensure the accuracy and real-time detection of faults and temperatures. Once a malfunction occurs or the temperature exceeds the set threshold, an alarm will be triggered to assist the staff in quickly locating the fault point.
· Automatic reset
After troubleshooting, the indicator can automatically reset within the set time or reset through remote control, reducing manual intervention.
· Remote communication
Some models have communication function with a RS485 interface, which can be connected to DTU for remote data transmission, and implement the standard State Grid IEC60870-5-101 protocol.
· Wide range adaptability
It’s suitable for different voltage classes and line types, with strong environmental adaptability.
· Easy installation and maintenance
Compact design, easy installation, suitable for live installation and removal, easy maintenance, and intelligent analysis.
