QYJFD-2000 Partial Discharge Detection System
0.0 0.0
Product description

The partial discharge detection system is a multi-function, multi-channel, automatic detection system for off-line partial discharge (PD) signal detection and diagnosis of full-voltage high-voltage electrical equipment.

Product Features

1. Powerful functions, advanced technology, meeting the latest national standard GB7354-87

2. New type of digital filtering and interference suppression function, so that on-site interference can be suppressed more effectively

3. With full program control automatic calibration, automatic synchronization, automatic voltage recording, automatic measurement storage and playback, etc.

4. With multiple view display modes such as sine and dot matrix, user operation and diagnosis are more convenient and free

5. The interactive user interface has a clear structure, friendly interface and convenient operation

6. Strong functional scalability, such as pulse polarity discrimination and partial discharge measurement in balanced loop mode

7. Miniaturized products, easy to use and carry

Product parameter

1. Detection sensitivity: <0.02pC

2. Number of detection channels: 2/4

3. Sampling rate: 20MHz/each channel

4. Sampling accuracy: 12Bit

5. Bandwidth selection: low end: 10, 20, 30, 80kHz? (OFF)

       High-end: 100, 200, 300, 1MHz? (OFF)

6. The error between the upper and lower cut-off frequency and its nominal value: no more than ±5%

7. Linearity error of apparent charge: ±5%

8. The corresponding asymmetry error of the apparent charge to the positive and negative pulses: ±5%

9. Range shift error of apparent charge: ±5%

10. Corresponding error of low repetition rate pulse of apparent charge: ±5%
