High-Voltage Variable Frequency Anti-Interference Dielectric Loss Tester
Darui Electric recommends
Features
1. Variable frequency anti-interference
Adopting variable frequency anti-interference technology, it can accurately measure even under 200% interference, with stable test data, suitable for on-site anti-interference dielectric loss tests.
2. High-precision measurement
Using digital waveform analysis and bridge self-calibration technologies, combined with high-precision three-terminal standard capacitors, it achieves high-precision dielectric loss measurement.
All ranges of the instrument have input resistance below 2Ω, eliminating the influence of additional capacitance from measurement cables.
3. Multi-level safety protection to ensure personal and equipment safety
High-voltage protection: In case of short circuit, breakdown, or high-voltage current fluctuation of the test object, it can quickly cut off the output in a short-circuit manner.
Low-voltage protection: In case of misconnection to 380V, power fluctuation, or sudden power outage, it activates protection without causing overvoltage.
Ground protection: When poor grounding of the instrument causes dangerous voltage on the shell, ground protection is activated.
C V T: Four protection limits for high-voltage current and voltage, and low-voltage current and voltage, preventing equipment damage; selecting the wrong menu will not output excitation voltage. No 10kV high-voltage output during CVT measurement.
