The PS-2000A is a cutting-edge, fully automated instrument designed for measuring the dielectric loss and volume resistivity of insulating oils and other insulating liquids. Developed by Baoding Push Electrical Appliance Manufacturing Co., Ltd., this device adheres to international standards such as ASTM D924 and GB/5654, ensuring reliability and accuracy in electrical testing. Its advanced features make it an essential tool for industries reliant on high-performance insulating materials, including power utilities, manufacturing, and research institutions.

Product Overview

The PS-2000A is a next-generation portable tester that combines automation, precision, and user-friendly design. It is specifically engineered to measure the dielectric dissipation factor (also known as the dielectric loss factor or tan delta) and DC resistivity of insulating oils. These parameters are critical for assessing the quality and performance of insulating materials used in transformers, capacitors, and other electrical equipment. The device’s ability to complete heating, dielectric loss measurement, and resistivity testing in a single operation significantly enhances efficiency and reduces human error.

Key Features and Advantages

1. High Automation and Integrated Workflow

The PS-2000A streamlines the testing process by integrating multiple functions into a single device. Users can perform heating, dielectric loss measurement, and resistivity testing without manual intervention, saving time and ensuring consistency. This automation is particularly beneficial in high-volume testing environments, where speed and accuracy are paramount.

2. Three-Electrode Structure for Enhanced Accuracy

Based on the GB/T 5654-2007 standard, the PS-2000A features a three-electrode structure with an inter-electrode spacing of 2mm. This design minimizes stray capacitance and leakage effects, which are common sources of error in dielectric loss testing. By eliminating these external influences, the device ensures that the results reflect the true properties of the insulating oil.

3. Advanced Heating and Temperature Control

The instrument employs medium-frequency induction heating combined with a PID temperature control algorithm. This non-contact heating method ensures uniform heating of the oil sample, with precise temperature regulation within a ±0.5°C range. The ability to maintain stable temperatures is crucial for accurate resistivity measurements, as thermal fluctuations can significantly affect results.

4. State-of-the-Art Signal Processing Technology

Utilizing DSP (Digital Signal Processing) and FFT (Fast Fourier Transform) technologies, the PS-2000A guarantees the stability, accuracy, and reliability of its data. These technologies enable the device to filter out noise and interference, producing clean and precise measurements even in challenging environments.

5. Internal Standard Capacitor for Long-Term Accuracy

The PS-2000A is equipped with an internal standard capacitor filled with SF6 gas. This design ensures that the capacitor’s capacitance and dielectric loss are unaffected by ambient temperature and humidity, maintaining accuracy over extended periods of use. This feature is especially valuable for laboratories that require consistent performance across multiple test sessions.

6. Intuitive User Interface

The device features a large color touchscreen that simplifies operation and enhances user experience. The interface allows for easy navigation, clear display of test results, and real-time monitoring of environmental conditions such as temperature and humidity. This user-centric design reduces the learning curve for new operators.

7. Safety-Centric Design

Safety is a top priority in the PS-2000A’s design. It includes a high-voltage electrode cup safety reminder that activates when the lid is removed, preventing accidental exposure to high voltages. This feature, along with precise temperature control, ensures the safety of both personnel and equipment during testing.

8. Real-Time Data Management

The PS-2000A records and displays real-time test data, including the date, time, and ambient conditions. It also allows users to store up to 100 sets of measurement data, which can be printed or exported for further analysis. This functionality is critical for compliance with industry standards and for maintaining a traceable record of tests.

9. Automatic Calibration and Correction

The device includes a correction function for empty electrode cups, enabling users to measure the capacitance and dielectric loss of the cup itself. This helps assess the cleaning and assembly quality of the electrode cup, ensuring that subsequent tests are free from contamination or structural issues. The calibration data is automatically saved, facilitating accurate calculations of relative capacitance and DC resistivity.
