SSWA – PD Testing (Online & Offline) & PD Survey

Water Corporation

SCOPE / SERVICES PROVIDED

SIGMA conducted both online and offline partial discharge (PD) testing for the Water Corporation, ensuring comprehensive monitoring and fault detection. Services provided included:

  • Online PD Survey for live equipment with minimal disruption.
  • Online and offline PD testing to analyse equipment health during live operations and scheduled shutdowns.

PROJECT EXECUTION

Key activities included conducting an online PD survey for live equipment, performing offline PD testing during planned shutdowns, and addressing challenges such as testing in a high-voltage 132kV GIS switchyard. SIGMA employed specialised tools and techniques to maintain safety and ensure accurate results.

CHALLENGES AND SOLUTIONS

The project encountered several challenges, including:

  • Live Equipment Testing: Conducting online PD testing required meticulous planning to ensure safety and equipment integrity.
  • Cable Fault Detection: A fault in the cable was detected during the pre-shutdown online PD survey, necessitating immediate rectification.
  • 132kV GIS Switchyard Operations: The high-voltage environment posed additional safety and operational risks.

To overcome these challenges, SIGMA applied best practices for live equipment testing, promptly addressed the cable fault in coordination with the client, and utilised specialised tools to conduct PD testing safely in a high-voltage environment.

OUTCOMES

SIGMA successfully delivered the project within the client’s timeframe, minimising risks and preventing equipment failures through early fault detection. The project reinforced SIGMA’s capability to conduct advanced diagnostic testing with minimal disruption, ensuring enhanced equipment reliability and operational efficiency.
