The GD-6000 variable-frequency anti-interference dielectric loss tester adopts variable-frequency power supply and digital filtering technology, and is suitable for dielectric loss factor (tanδ) and capacitance measurement in substation field and laboratory environments. The instrument has a built-in variable-frequency power supply and can output test voltage at two frequencies, 45Hz and 55Hz. Combined with relevant algorithms, it effectively suppresses power-frequency interference and improves the stability of on-site measurement.
1. Supports automatic measurement of dielectric loss factor (tanδ) and capacitance (Cx), with measurement results displayed directly.
2. Equipped with CVT self-excitation measurement function, enabling measurement of capacitive voltage transformers without disconnecting wires.
3. Provides multiple measurement modes such as forward connection, reverse connection, and CVT self-excitation, adapting to the needs of different test samples.
4. Built-in overcurrent, overvoltage, and short-circuit protection ensures the safety of the testing process.
5. Supports data storage and query, and measurement records can be exported.
