Product Overview
Use sensors to capture the phenomenon of partial discharge. Common sensors include ultrasonic sensors, pulse current sensors, ultra-high frequency (UHF) sensors, etc. The signal detected by the sensor is conditioned digital signal through the signal processing unit circuit for filtering and amplification, and then further processed and analyzed to extract the characteristic parameters of partial discharge through the analog-to-digital converter (AND converter) and converted into a digital signal.

Q: What is partial discharge (PD)?
A: Partial discharge is a localized electrical discharge that partially bridges the insulation between conductors, causing degradation over time. Early detection of PD helps prevent transformer failures.
Q: How does the system detect partial discharge?
A: The system uses multiple sensors (ultrasonic, pulse current, UHF, HF) to capture PD signals. These signals are processed, filtered, and analyzed to extract characteristic parameters and convert them into digital signals.
Q: What are the benefits of real-time monitoring?
A: Real-time monitoring allows for immediate detection of PD events, enabling proactive maintenance and reducing downtime.
Q: Is the system compatible with existing transformer installations?
A: Yes, the system supports various sensor types and can be easily integrated into existing transformer setups.
Q: Can the system be accessed remotely?
A: Yes, the system includes remote monitoring and internet access for real-time data analysis and diagnostics.
Q: What is the operating temperature range?
A: The system operates reliably between -40°C and +80°C.
