ZY-PDL5000 partial discharge detection and positioning system

ZY-PDL5000 partial discharge positioning system is mainly used for partial discharge detection and positioning of high-voltage electrical equipment. The system consists of an ultra-high frequency sensor, an ultrasonic sensor, an ultrasonic preamplifier, a high-frequency current sensor, a signal processing system, and a high-speed oscilloscope. The system adopts a self-developed digital adjustable band signal processing system. In the UHF band, the lower frequency limit can be adjusted to avoid the interference of low frequency noise.

product description
[[[[产品参数, 参数]]]]
　　ZY-PDL5000 partial discharge positioning system is mainly used for partial discharge detection and positioning of high-voltage electrical equipment. The system consists of an ultra-high frequency sensor, an ultrasonic sensor, an ultrasonic preamplifier, a high-frequency current sensor, a signal processing system, and a high-speed oscilloscope. The system adopts a self-developed digital adjustable band signal processing system. In the UHF band, the lower frequency limit can be adjusted to avoid the interference of low frequency noise. The oscilloscope uses the domestic top RIGOLDS6015 series, the analog bandwidth is 1G, and the sampling frequency is up to 5GS / S , Can accurately and quickly capture the signal details generated by partial discharge.
　　ZY-PDL5000 partial discharge positioning system can be used for ultra-high frequency positioning, ultra-high frequency, ultrasonic joint positioning and detailed observation of partial discharge signals.
