Executive Summary

Partial discharge (PD) is a critical early indicator of insulation degradation in dry-type transformers. Left undetected, PD can lead to catastrophic failures, costly downtime, and compromised safety. The PTSDTX™ system from Power Technologies™ offers a comprehensive, AI-driven solution for real-time PD monitoring, combining advanced sensor technology, predictive analytics, and intuitive software to safeguard transformer health and extend operational life.

  1. Introduction: The Challenge of Partial Discharge in Dry-Type Transformers

Dry-type transformers are essential components in modern power systems, especially in environments where fire safety and environmental resilience are paramount. However, long-term operation leads to insulation aging, which manifests as partial discharge – localized electrical discharges that do not completely bridge the insulation between conductors.

Types of Partial Discharge:

  • Internal Discharge: Occurs within solid insulation due to defects, voids, or cavities that trap electric fields.

  • Surface Discharge: Develops along the surface of insulating materials, often triggered by contamination or moisture.

  • Contact Discharge: Arises when floating conductive elements are exposed to high electric field conditions, leading to localized breakdown.

  • Corona Discharge: Happens in gaseous dielectrics under inhomogeneous electric fields, typically around sharp edges or points, producing ionization without complete breakdown.

These discharges, though initially weak, accelerate insulation deterioration and can trigger severe short-circuit failures if not addressed proactively.

  1. Monitoring Methodology: AI-Enhanced Detection and Diagnosis

The PTSDTX™ system employs a multi-sensor, AI-powered approach to detect and analyze PD activity with high precision. Unlike traditional methods (pulse current, gas chromatography), PTSDTX™ leverages Ultra High Frequency (UHF) detection for superior noise immunity and broader data capture.

Key Monitoring Technologies:

  • HFCT Sensor (PTSPD32)
    Mounted on the iron core ground wire, offering high sensitivity and low-frequency noise filtering.

  • UHF Sensor (PTSPD33)
    Non-intrusive magnetic installation with IP65-rated durability, ideal for dusty or wet environments.

  • Self-Powered Wireless Temperature Sensor (PTSPS061)
    Wireless Portal-based, battery-free monitoring for isolated high-voltage zones.
