Application for lightning impulse voltage full-wave, lightning impulse voltage chopped-wave (optional) and impulse voltage switching surge (optional) test of electrical equipment and other test products, to check insulation performance.

Features:

◆Stable waveform,the control and measurement system used is a mature product in China. The core component is the FX system programmable controller of Mitsubishi Corporation of Japan. Almost all control functions are realized by software programming. Therefore, the system has a simple structure, few peripheral circuit boards, high reliability.

◆Full automatic control,the operation interface of the control and measurement system adopted fully considers the customary characteristics of high-voltage tests, which is simple and clear, and is convenient for testers to operate. The system has designed a special program operation interface, which greatly simplifies the operation of the test personnel and can effectively prevent human errors.

◆Long service life,this set of lightning impulse voltage generator test system adopts advanced technology, good craftsmanship and high-quality raw materials, which can ensure long-term use and operation life of more than 20 years. The usual running costs are also low.

◆The main structure adopts the current compact generator, which has the characteristics of small inherent inductance and convenient wave adjustment.

◆Integrated overall design of measurement and control structure,adopt optical fiber control transmission system realizes the optical fiber connection between the control measurement equipment and the high-voltage main equipment, effectively solves the harm to the measurement and control system caused by the elevated ground potential encountered in the high-voltage test, and eliminates the electromagnetic interference caused by the control leads. Highly improves the reliability of the system.
