Product Description

The partial discharge detector is a newly developed digital liquid crystal display partial discharge detector that our company has developed to address the problems of low brightness and short lifespan of traditional partial discharge detector oscilloscopes.
This instrument maintains the advantages of mature models, such as high detection sensitivity, wide coverage of test sample capacitance, wide applicability to various test samples, complete input units (detection impedance), and multiple frequency band combinations (nine types). The operation and structural installation are fully compatible with previous models, facilitating the upgrade and renovation of existing system equipment. It can directly upgrade existing models such as KJF2004, KJF2002, and KJF2000.
Product Features
◆ After digital processing of partial discharge signals, a liquid crystal display is used to replace the traditional oscilloscope display.
◆ The operation is exactly the same as traditional analog partial discharge test instruments, making it easy to learn.
◆ Free selection of elliptical, linear, and sinusoidal display modes.
◆ Digital windowing technology is adopted to avoid the influence of interference on measurement.
◆ Arbitrary phase windowing, single or dual windows optional, with 150-degree rotation of the ellipse.
◆ The current discharge pattern can be frozen and saved for static observation and analysis of partial discharge pulses.
◆ The current discharge pattern can be saved to ensure traceability of test results.
