Advantages of GIS On-Line Monitoring System
Ang paglipat mula sa oras na batay sa pagpapanatili ng batay sa kondisyon
Tradisyonal time-based maintenance strategies schedule GIS inspections and component replacements at fixed calendar intervals (hal., 5-year major inspections, 10-year overhauls) regardless of actual equipment condition. This approach results in unnecessary maintenance on healthy equipment and potential failures of degraded equipment between scheduled interventions.
Early Fault Warning Capabilities
Progressive fault development in GIS typically follows detectable stages before catastrophic failure. Partial discharge activity increases gradually over months or years as insulation degrades. Contact resistance rises incrementally as erosion accumulates. Mechanical wear produces subtle changes in operating characteristics long before complete mechanism failure.
Equipment Service Life Extension
GIS design life karaniwang saklaw mula sa 30 sa 40 years under normal operating conditions with appropriate maintenance. Gayunpaman, actual service life depends heavily on operating stress levels, Mga kondisyon sa kapaligiran, at kalidad ng pagpapanatili. Monitoring systems extend service life by detecting conditions that accelerate aging (sobrang init, Kontaminasyon ng kahalumigmigan, excessive PD activity) while they remain correctable through minor interventions such as re-torquing connections, gas processing, or localized cleaning.
Power Supply Reliability Enhancement
Grid reliability metrics including System Average Interruption Duration Index (Ang site) and System Average Interruption Frequency Index (LIGTAS) improve measurably when utilities implement comprehensive GIS monitoring. Forced outage reduction results from early detection and planned correction of developing faults.
Applications of GIS On-Line Monitoring System
Extra-High Voltage and Ultra-High Voltage Substations
EHV and UHV transmission substations represent the most demanding application environment for GIS technology. At voltage levels of 245 KV, 420 KV, 550 KV, 800 KV, at 1100 KV, GIS installations form the critical switching infrastructure for national and regional power grids.
Urban Center Distribution Substations
Metropolitan areas face severe land constraints, paggawa compact GIS substations the preferred solution for 72.5 kv to 145 kV distribution networks. These installations frequently occupy underground locations beneath parks, commercial developments, or transportation infrastructure.
Power Generation Plant Switchyards
Generator step-up (GSU) transformers and switchyard GIS at thermal, nuklear, hydroelectric, and renewable energy power plants handle the transition from generator voltage levels (Karaniwan 13.8-24 KV) to transmission voltages. These installations experience frequent switching operations during unit startup, synchronization, and shutdown sequences, plus continuous operation during steady-state generation.
Industrial Power Distribution Systems
Large industrial complexes including steel mills, petrochemical refineries, cement plants, Mga operasyon sa pagmimina, and manufacturing facilities deploy medium-voltage GIS (12-40.5 KV) for incoming utility feeds, on-site generation interconnections, and critical process load distribution.
GIS vs Traditional Air-Insulated Switchgear (Ais) Paghahambing
