Products Name：
HNPRX-1000 Capacitive Equipment Online Monitoring System
Overview
HNPRX-1000 capacitive equipment online monitoring system can online monitor and diagnose the real-time status parameters of equipment such as transformer bushing, capacitive voltage transformer and coupling capacitor in the substation; monitoring includes monitoring of dielectric loss, leakage current and equivalent capacitance, etc. of the capacitive equipment, and diagnosis includes fault judgment, fault diagnosis, fault seriousness and development trend analysis, fault hazard evaluation and repair strategy etc.
It mainly consists of sensor module, IED module, control host and monitoring & diagnosis system, etc. The locally installed equipment has an enclosure protection level above IP45, and adopts RS485 bus architecture to facilitate installation and wiring. The standard control host is Advantech 510 series, the serial ports can be expanded, or a higher quality of industrial control host can be selected, and there is a 19" standard cabinet for mounting. The monitoring & diagnosis system is developed independently by HNP and is compatible with XP or later versions of the operating system. Through years of version updating, the system has complete functions and humanized operation.
