The substation preventive diagnostic system is a system that monitors the status of transformers, switches, circuit breakers, and other power equipment in real time and detects abnormal signs early to prevent failures. Applying the latest technology can increase the reliability of substations and reduce maintenance costs.
The main element of transformer monitoring is to comprehensively collect and analyze information such as oil temperature, pressure, gas in oil, partial discharge, and bushing status, and transmit the data to the monitoring system to realize transformer preventive diagnosis.
This system can diagnose abnormal signals occurring inside the device at an early stage to prevent accidents. The main monitoring elements are GIS partial discharge diagnosis, circuit breaker diagnosis, gas analysis diagnosis, and lightning arrester diagnosis. The information is comprehensively collected and analyzed and transmitted to the monitoring system to realize GIS/GCB preventive diagnosis.
It enables preventive cable diagnosis by early detection of insulation abnormalities caused by deterioration of ultra-high voltage cable lines, such as trauma, thermal, electrical, and mechanical stress.
Batteries serve as emergency power supplies in substations, UPS (uninterruptible power supplies), power facilities, and communication base stations. Since a decline in battery performance can lead to disruption in power supply, it is essential to use a battery diagnostic device to precisely analyze the battery condition and perform preventive maintenance.
