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.
