HCL2796 Transformer Turn Ratio Meter (Single phase)

Lead time: 30 days

Mode: HCL 2796
Description: 
HCL2796 transformer turn ratio meter is special designed for power transformer (single phase & three phases) and instrument transformer testing, suitable for testing in substation, transformer manufacturer, meter manufacturer. It helps to detect faulty transformer winding and tap changer position. It’s fully automatic device, can recognizes winding connection and vector group number of transformer winding. The user only need connect measuring cable and press start button and come out the test result.
Transformer ratio changing reason
Deteriorated insulation
Physical damage
Contamination
Shipping damage
If the deviation of transformer ratio and its rated turn ratio more than 0.5, its may not operate reliably. To measure small ratio changes, we need high quality accuracy turn ratio meter HCL2796.
