Key words:

As a new wave of cold sweeps across China, power loads in multiple regions have been on a continuous rise. Surging winter heating demand coupled with fluctuating output of new energy sources has pushed the power grid into its annual "supply guarantee test". As an integrated energy service provider with nearly 20 years of experience in the power industry, Sitech Electric has built a full-chain product-and-service matrix covering equipment monitoring, diagnosis, testing and operation & maintenance based on its two core technical pillars of "Digital Smart Grid" and "Smart Energy", providing solid technological support for ensuring a safe, efficient and stable power supply during the winter peak demand period.

01 Product + Service: Full-Scenario Protection for Winter Power Grid Security

In response to the challenges of high operational pressure and elevated hidden danger risks of power grid equipment during the winter peak demand season, Sitech Electric provides full-cycle protection for the safe operation of equipment by virtue of its power product and service matrix covering the entire life cycle.

Products: Multi-Dimensional Monitoring for Early Hidden Danger Detection

Transformer Integrated Online Monitoring System adopts a "hardware-software integration" design concept. On the hardware side, it integrates multi-dimensional sensors for oil chromatography, partial discharge, temperature, bushing dielectric loss and other key parameters to enable simultaneous data collection. On the software side, it leverages AI diagnostic models to deliver accurate early warning and intelligent diagnosis of latent and sudden transformer faults. This effectively addresses long-standing industry pain points such as slow response and high misjudgment rates caused by heavy reliance on manual work and outdated standards in traditional monitoring methods.

Professional Verification for Traceable Hidden Dangers

Live Detection: Integrates infrared, ultraviolet, ultrasonic, ultra-high frequency, transient earth voltage and high-frequency partial discharge technologies to detect equipment anomalies such as abnormal discharge and overheating without power interruption.

X-ray Detection: Uses penetrating imaging technology to conduct visualized diagnosis of internal structures of critical components including GIS equipment and tension clamps.

Power Testing: Covers commissioning, preventive and grid-connected tests of equipment, quantitatively evaluating equipment health status through insulation performance, withstand voltage and other tests.

Intelligent Operation & Maintenance: Deeply integrates AI and IoT technologies to achieve 7×24-hour panoramic perception, intelligent early warning and automatic generation of operation and maintenance reports for equipment and their surrounding environment.

Offline Rapid Response: Combines professional teams with standardized processes to ensure that warnings are processed within 10 minutes and faults are resolved on-site within 2 hours to form a closed-loop disposal.

This product-and-service matrix has been verified in over 12,000 substations and more than 1,000 customer projects nationwide, helping clients reduce operation and maintenance costs by 30% and achieve a fault early warning accuracy rate of over 95%.

02 Practical Expertise: Integrated Live Detection Services for Energy Bases

At a large-scale energy base in Xinjiang, Electric provided integrated live detection services for substations of all voltage levels ranging from 35kV to 220kV. The project covered core testing items including infrared thermal imaging detection of primary equipment, GIS partial discharge detection, transformer partial discharge detection and arrester leakage current detection, achieving comprehensive and thorough diagnosis of the operational status of key equipment.

Located deep in the Gobi Desert, the project was subjected to harsh environmental conditions. Relying on high-precision testing equipment and standardized operation procedures, Sitech Electric's technical team accurately identified equipment hidden dangers, ensuring the safe and stable operation of the power grid under extreme cold and sandy conditions. The project has won high recognition from the client and set a benchmark for regional power operation and maintenance.

With the cold wave continuing to rage, power grid supply guarantee has entered a critical phase. Backed by its global service centers and professional teams, Sitech Electric will continue to provide round-the-clock protection for the safe operation of power equipment with its mature product and service system and rich project experience, safeguarding warmth and light for all during the winter season.
