On-line Monitoring System of Transformer Core Grounding Current

The LHTX1306B transformer core/clamp grounding online monitoring system captures instantaneous current changes online in real time, and sends out alarm signals through analysis and judgment to provide accurate and direct judgment basis for operators to assist operators to eliminate core/clamp grounding faults in time. The stored historical data provide basis for condition-based maintenance, evaluation, early warning and risk analysis of transformers, and are powerful tools to ensure safe operation of transformers.
