Oil Dissipation Factor Analyzer Oil Resistivity Dielectric Loss Equipment For Laboratory Testing
GDGY Automatic Insulating Oil Tan Delta Resistivity Tester is a professional high-precision testing instrument designed for analyzing key electrical properties of insulating oil. It integrates multiple core functions, including dielectric loss angle (tgδ) measurement, volume resistivity (ρ) testing, and capacitance (Cx) detection, making it an essential tool for power utilities, transformer manufacturers, petroleum refineries, and electrical testing laboratories.
Dual Core Test Functions: Simultaneously measures dielectric loss (tgδ) and volume resistivity (ρ), and automatically calculates relative dielectric constant (ε), insulation conductance (Gx), and volume conductivity (σ), providing comprehensive oil performance data.
High-Frequency Induction Heating: Non-contact heating between the oil cup and heating unit ensures uniform heating, fast temperature rise (room temperature to 100℃ in <20min), and easy temperature control, avoiding oil pollution caused by traditional heating methods.
Stable Test Power Supply: Adopts AC-DC-AC conversion mode for the AC test power supply, eliminating the impact of grid voltage and frequency fluctuations. It can operate normally even when powered by a generator.
High-Precision Standard Capacitor: Built-in SF6 three-pole gas-filled standard capacitor, whose dielectric loss and capacitance are not affected by environmental temperature and humidity, ensuring long-term measurement accuracy.
Intelligent Operation & Control: Full-automatic measurement with Chinese operation prompts. Supports three test modes (direct test, heating test, automatic test) to meet different test scenarios.
Comprehensive Data Management: Stores test data with power-off memory function, supports USB export (TXT format) and on-site printing. Historical data can be easily queried and archived.
User-Friendly Design: 7-inch large touch screen, simple operation interface, and detachable oil cup (triple-terminal structure, 40ml capacity) for easy cleaning and oil sample replacement.
