HYJD-2 Insulating Oil Tan Delta & Volume Resistivity Tester | Transformer Oil Dielectric Loss Tester

The HYJD-2 measures the dielectric loss factor (tan delta) and volume resistivity of transformer and insulating oils to assess insulation condition and detect moisture, aging, and contamination. Designed for new-oil acceptance testing and routine oil condition monitoring, it is suitable for transformers, high-voltage switches, cables, capacitors, and other power equipment.

Detailed Description

Key Features

Fast & Uniform Temperature Control
Medium-frequency induction heating combined with precise PID temperature control enables contact-free, uniform, and rapid heating of insulating oil, improving test efficiency and temperature stability.
High-Stability Measurement Reference
Built-in SF₆ gas-filled three-electrode standard capacitor provides a highly stable measurement reference, helping maintain accurate and reliable test results with minimal influence from ambient temperature and humidity.
Advanced Power Supply & Anti-Interference Design
The AC-DC-AC conversion power supply effectively isolates fluctuations in grid voltage and frequency, ensuring stable testing performance even when powered by a generator.
