Product Introduction
The Transformer Core Grounding Current On-line Monitoring System is a professional-grade solution designed to track the operational status of transformers in real time by measuring both the core grounding current and the clamping component grounding current. This system helps prevent potential transformer failures caused by accidental multiple grounding of the core. Our Transformer Core Grounding Current On-line Monitoring System comprises core monitoring hardware and backend software, forming a comprehensive monitoring platform. The hardware utilizes a through-core sampling architecture and connects to the backend system via wired or wireless communication channels, thereby ensuring reliable remote data transmission.

FAQ
Q: Are the alarm thresholds for the Transformer Core Grounding Current Online Monitoring System configurable?
A: Multiple alarm levels can be set for tiered early warning.
Q: What are the functions of the backend software?
A: Real-time display, trend curves, report statistics, and alarm management.
Q: Will the normal operation of the transformer be affected after the system is installed?
A: No, you can be assured it will not. The core of our design is a non-intrusive sampling technique that requires no alteration to your transformer. The monitored unit continues to run exactly as it did before, with no measurable impact from our monitoring device.
