Our product is a complete solution for the online monitoring and diagnosis of grounding current of high-voltage transformer cores and clamping parts, suitable for power transformers and traction transformers at voltage levels of 110KV and above. The product passes the EMC electromagnetic interference test in accordance with the GB/T17626 industry standard, and mainly consists of current sensors, on-site collection units, and backend analysis systems. Real-time monitoring data is processed and analyzed, then transmitted to the main station via a local area network, capable of outputting 4-20mA signals and complies with the State Grid or Southern Grid 61850 communication protocol.
Monitoring reasons: Core failure may cause local overheating, insulation breakdown or even explosion. Monitoring can provide early warning to avoid system paralysis.
