PS-2000A Insulating Oil Dielectric Loss Tester-Baoding Push Electrical Appliance Manufacturing Co., Ltd.

The PS-2000A is a cutting-edge solution designed for precise measurement of dielectric loss and volume resistivity in insulating oils. Developed by Baoding Push Electrical Appliance Manufacturing Co., Ltd., this device combines advanced technology with user-friendly features to meet the demands of modern electrical testing. Below is a comprehensive overview of its capabilities, specifications, and applications.

Product Features

The PS-2000A stands out for its high automation and integrated functionality. It performs heating, dielectric loss measurement, and volume resistivity testing in a single operation, significantly reducing testing time and human error. The device employs a three-electrode structure compliant with GB/T 5654-2007, ensuring accurate results by minimizing stray capacitance and leakage effects. This design is critical for industries relying on precise insulation quality assessments, such as power transformers and electrical equipment manufacturing.

One of the key innovations is the use of medium frequency induction heating with a PID temperature control algorithm. This non-contact heating method ensures uniform temperature distribution, maintaining accuracy within a ±0.5°C range. The device also incorporates DSP (Digital Signal Processing) and FFT (Fast Fourier Transform) technologies, enhancing data stability and reliability. These features are particularly beneficial for environments where consistent performance is paramount, such as in NIST (National Institute of Standards and Technology) accredited laboratories.

The PS-2000A includes an internal standard capacitor filled with SF6 gas, which remains unaffected by ambient temperature and humidity. This ensures long-term accuracy, even after extended use. The device’s large color touch screen simplifies operation, while the real-time clock allows for date-stamped data storage and printing. Additional safety features, such as a high-voltage electrode cup short reminder, protect operators and equipment from hazards.
