It is suitable for local discharge measurement of all kinds of high voltage electrical equipment and represents the advanced technology of domestic digital local discharge instrument
JFD-2000APartial discharge detection system it is the main test item of power equipment insulation, local discharge and other parameters are important indexes to evaluate the quality of power equipment. Jfd-2000 apartial discharge detection system is a new generation member of successful HTJF series. In addition to the inherited generation product advantages, the products have full program-controlled automatic calibration, automatic synchronization, automatic voltage record, automatic measuring preservation playback function, can be repeated measurements such as discharge rate n, average discharge current I, D square rate such as IEC - 270 under various parameters and partial discharge using sine, lattice view shows a variety of ways, a new type of digital filter and interference suppression function, statistical analysis combined with abundant dynamic map, make field interference can be more effectively suppressed, user operation and easy diagnosis more easily. With the continuous development of the software, its functions are also constantly expanded, such as pulse polarity identification and balance circuit mode partial discharge measurement and other functions.
JFD-2000apartial discharge detection system completely conforms to the new GB7354 and iec-270-ldquo in terms of its detection method, measurement circuit and technical performance parameters. Partial discharge measurement ” Standard requirements. Suitable for local discharge measurement of all kinds of high voltage electrical equipment, covering the full voltage and capacity level, representing the advanced technology of domestic digital local discharge instrument.
