Product Description
Automatic Digital Power Frequency Dielectric Loss & Tanδ Tester for Transformers
This automatic anti-interference precision medium loss measuring instrument is designed for both field anti-interference dielectric loss measurement and laboratory precision dielectric loss measurement. The integrated structure features built-in dielectric loss bridge, frequency conversion power supply, test transformer, and standard capacitor.
Utilizing frequency conversion anti-interference and Fourier transform digital filtering technology, the instrument performs automatic and intelligent measurements. The measured data remains exceptionally stable under strong interference conditions. Measurement results are displayed on a large LCD screen and can be printed using the integrated micro printer.

Important Note: On-site transformer housing is generally grounded. When testing the tanδ (dielectric loss) of transformers, the reverse connection method is generally selected. Only for fully insulated transformers is the forward connection method used for testing.
Capacitance Conversion Reference:
1F = 1000mF = 1,000,000,000μF = 1,000,000,000,000pF
1mF = 0.001F = 1000μF = 1,000,000,000pF
1μF = 1,000,000pF = 0.000001F
1F = 1000mF = 1,000,000,000μF = 1,000,000,000,000pF
1mF = 0.001F = 1000μF = 1,000,000,000pF
1μF = 1,000,000pF = 0.000001F
