Product Description

GDRB-Ⅱ Transformer Frequency Response Tester Detects Transformer Winding Movements And Mechanical Failures Due To Mechanical Shock, Transportation Or Short Circuits. Detection Of These Displacements Ahead Of A Dielectric Failure Can Reduce Unplanned Maintenance Costs, And Provide The Possibility To Improve System Reliability By Preventing Outages. Additionally, When Damage Is Discovered, Repairs May Be Targeted To A Specific Phase Winding. GDRB-Ⅱ Can Detect All Level Power Transformers.
