Description

Seeing the unseen hazards. Protecting the power heart with silent, smart vigilance.

For the Heying Data Rayong project in Thailand, we supply an online partial discharge monitoring system for transformer. Designed for Thailand's tropical climate, the system operates reliably under high temperature and humidity conditions.

Delivered in 2026, the SUN-IGuard-503 model complies with IEC 60270 and features three monitoring channels. Finished in RAL7032, it supports AC220V, 50Hz power supply and RS485 communication.

Equipped with high-sensitivity PD sensors and intelligent algorithms, the system detects insulation defects, corona, and surface discharges, enabling early identification of partial discharge faults for predictive maintenance. Remote data transmission supports seamless integration with the Heying Data monitoring platform for unattended operation.

Our solution delivers reliable transformer health management for the Thailand Heying Data Rayong project, enhancing power system safety and intelligence.

Unlike conventional methods, UHF sensors avoid low-frequency interference (e.g., corona, switching noise), ensuring a high signal-to-noise ratio. They detect pico-coulomb discharges early, enabling identification of incipient faults. In arrays, they support rough spatial localization via time-difference-of-arrival (TDOA). Operating non-intrusively and in real time, they also help classify PD types (e.g., floating particles, voids) through spectral analysis. Together with HFCT and ultrasonic sensors, they strengthen a multi-sensor diagnostic system.

Protect the internal circuit board, signal acquisition module, and power supply from dust, moisture, vibration, and electromagnetic interference. Provide standardized installation interfaces (bottom aviation plug/cable interface) for easy access to sensor signals and power supply.

In conclusion, the online partial discharge monitoring system for transformer for Thailand's Heying Data Rayong project delivers reliable, internationally compliant performance for critical power infrastructure in Southeast Asia. Designed for Thailand's tropical climate, the system operates stably under high temperature and humidity conditions.

Delivered to Thailand in 2026, the SUN-IGuard-503 model complies with IEC 60270 and monitors partial discharge across three channels. Finished in RAL7032, it is powered by 220VAC/50Hz with RS485 communication, enabling early detection of insulation defects, corona, and surface discharges to support predictive maintenance. The system's remote transmission capability lays the groundwork for AI-driven insulation health prognosis, turning raw partial discharge data into actionable degradation trends. This digital layer not only minimizes unplanned outages but also empowers the Rayong facility to evolve from reactive maintenance to a true condition-based, asset-centric reliability strategy.
