Online Monitoring and Recording

IGES can compensate for the blind spots in the monitoring and protection of existing substation grounding networks, and is a comprehensive early warning and defense system that realizes digital and intelligent management of substation grounding networks. IGES can provide multi-point and multi-dimensional real-time online monitoring and waveform recording, comprehensively monitor system grounding safety hazards, have warning functions, and have the ability to actively defend against various overvoltage and grounding safety hazards in the secondary system.

The main functions of the IGES intelligent ground grid warning and defense system include: (1) providing online protection functions such as secondary overvoltage, ground potential counterattack overvoltage, and ground grid interference suppression; (2) Provide real-time data monitoring function for important parameters such as grounding impedance, grounding current, grounding grid potential, and spectrum analysis; (3) Provide pre alarm functions such as grounding impedance exceeding limit, ground potential exceeding limit, power supply voltage and current exceeding limit, etc; (4) Provide a digital management platform, providing online display of major electrical parameter data and waveforms, historical records, important event records, warning and defense, etc.

CAFS is developed based on the actual operating characteristics of 6kV~110kV power cables. It adopts a layered distributed structure and integrates various advanced digital technologies to adapt to harsh operating environments. It monitors the insulation status of power cables in operation and analyzes transient traveling waves of power cable grounding wires in real timeSignal characteristics, early detection of insulation faults in power cables and timely prediction, to avoid power outages caused by sudden cable failures and improve power supply reliability.

RONS accurately captures all the details of nanosecond level peak overvoltage, and is a microscope and magnifying glass for transient overvoltage. The RONS peak overvoltage nanosecond level recording analyzer has three major functions: monitoring, recording, and analysis. RONS has a high sampling frequency of 20MHz and can monitor the voltage and current of the system in real-time online. It can record the voltage and current fault waveforms of the system for a long time.

RAVS is a monitoring device specifically designed for online long-term high-frequency recording of sudden changes in system voltage. RAVS can monitor system voltage in real-time online, monitor voltage fluctuations and power quality of the system, and has the characteristics of high accuracy, high precision, high response speed, and high stability.

RAVS is unable to accurately capture information on short duration system voltage fluctuations using commonly used waveform recorders or power quality monitoring devices in the market. RAVS can accurately monitor and record the changes in system voltage for a long time, and conduct real-time analysis of voltage issues such as voltage flicker, voltage oscillation, voltage deviation, voltage surge, voltage grounding, voltage short circuit, etc. Based on the recorded analysis results, it provides accurate quantitative parameters and reasonable solutions for fault warning, fault analysis, and fault resolution.In addition, RAVS can also perform real-time online monitoring of conventional power quality such as system voltage, current, power, THD, and imbalance.
