HVEX | Tangent Delta (Loss Factor) and Capacitance Tester

Technical Information

Power Supply

180 ~ 270 V, 50 Hz/60 Hz ± 1 %

Measurement Time

approximately 30 s (Related to measurement method)

Uncertainties

Capacitance Cx: ± (reading x 1% + 1pF); tan δ: ± (reading x 1% + 0.00040)

Anti-Interference

Frequency conversion anti-interference, less than 200% interference, achieves high precision

Capacitance Measurement Range

Internal AT terminal (3 - 60000 pF/12 kV and 60 pF - 1 μF/0.5 kV); External AT terminal (3 pF - 1.5 μF/12 kV and 60 pF - 30 μF/0.5 kV) with max resolution of 0.001 pF (4 significant digits)

Precision and efficiency

With an internal source of up to 12 kV or the option to use an external source and capacitor, this device offers versatile applications, adapting to different testing needs, including high-voltage applications. Highlighting its precision, the Tangent Delta uses digital waveform analysis and bridge self-calibration technology. Its multi-level protection ensures operational safety, with rapid response in cases of short-circuit or dielectric breakdown at the AT terminals.
