The PS-2000A Insulating Oil Dielectric Loss and Volume Resistivity Tester is a cutting-edge instrument designed to measure the dielectric loss and volume resistivity of insulating oils and other dielectric liquids. Developed by Baoding Push Electrical Appliance Manufacturing Co., Ltd., this device combines advanced technology with user-friendly design to ensure precise and reliable testing in industrial and laboratory settings. Below is a comprehensive overview of its features, specifications, and applications.

Key Features and Advantages

The PS-2000A stands out due to its high automation and precision engineering, making it an ideal tool for professionals in the electrical and power industries. Here are its core advantages:

1. Integrated Automation: The device streamlines the testing process by completing heating, dielectric loss measurement, and resistivity testing in a single operation. This reduces human error and saves time, ensuring efficient workflows.
2. Three-Electrode Structure: Adhering to the GB/T 5654-2007 standard, the three-electrode configuration with a 2mm inter-electrode spacing minimizes stray capacitance and leakage effects, enhancing the accuracy of dielectric loss measurements.
3. Advanced Heating Technology: Utilizing medium frequency induction heating and a PID temperature control algorithm, the PS-2000A ensures uniform heating, non-contact operation, and precise temperature regulation within a ±0.5°C error margin. This is critical for maintaining consistent test conditions.
4. DSP and FFT Technology: The integration of DSP (Digital Signal Processing) and FFT (Fast Fourier Transform) ensures stable, accurate, and reliable data collection, even under varying environmental conditions.
5. Internal Standard Capacitor: The device features an SF6-charged three-pole capacitor that remains unaffected by ambient temperature and humidity, guaranteeing long-term measurement accuracy.
6. Intuitive Interface: A large color touch screen simplifies user interaction, allowing operators to navigate the system with ease and view test results clearly.
7. Safety Enhancements: The PS-2000A includes a high-voltage electrode cup short-circuit reminder when the lid is open, significantly reducing the risk of accidents during testing.
8. Data Management: With real-time clock functionality, the device automatically saves test dates, times, and environmental data (e.g., ambient temperature). It can store up to 100 sets of measurement data for future reference.
9. Correction Function: The empty electrode cup correction feature measures capacitance and dielectric loss factors of the empty cup to assess its cleanliness and assembly status, ensuring accurate calculations of relative capacitance and DC resistivity.
