Intelligent Dielectric Loss Tester Features
1. Frequency conversion anti-interference
Adopting frequency conversion anti-interference technology, it can still measure accurately 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 lower than 2Ω, eliminating the influence of additional capacitance of the measuring cable.
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, the output can be cut off at high speed in a short-circuit manner.
Low-voltage protection: In case of accidental connection to 380V, power fluctuation, or sudden power failure, protection is activated without causing overvoltage.
Grounding protection: When poor grounding causes dangerous voltage on the shell, grounding protection is activated.
C V T: Four protection limits for high-voltage voltage and current, low-voltage voltage and current, will not damage the equipment; wrong menu selection will not output excitation voltage. No 10kV high-voltage output during CVT measurement.
