Testermeter- JYZ-HW Remote Overhead Line Fault Indicator
Product Overview
| The JYZ-HW is designed for 5–38kV overhead line distribution networks (customizable up to 44kV, 69kV, or 110kV) to detect and indicate short-circuit and earth faults. It transmits fault signals via ultra-bright LEDs and uploads fault data to SCADA systems using 2.5G/3G/4G networks. The device supports live-line installation and bidirectional wireless parameter adjustment. |
